  main limitations imposed by uncertain input physics in the models and by 
 external constraints (aka solar abudances)\, and discuss the current const
 raints imposed from helioseismic and solar neutrino measurements. Also\, I
  will discuss the implications that our current limitations in modeling th
 e Sun have for stellar physics. Finally\, some discussion will be devoted 
 to the importance of a prospective measurement of solar neutrinos from the
  CN-cycle would have for solar models and other fields.\n\nhttps://indico.

DESCRIPTION:Speakers: Jeff Hartnell ()\nIn this talk I will present a pote
 ntially game-changing new particle detector technology called LiquidO. Thi
 s idea turns the concept behind the widespread scintillator detectors on i
 ts head: for 50 years research has focussed on making more and more transp
 arent scintillator materials\, whereas LiquidO actually requires an opaque
  scintillator. In LiquidO\, scintillation light is confined near its creat
 ion point due to a short scattering length and collected by a dense grid o
 f wavelength shifting fibres. The resulting topological information\, norm
 ally lost in transparent LS detectors\, allows for powerful event-by-event
  particle identification including MeV-scale positrons\, electrons and gam
 mas\, enabling strong background suppression. Another advantage over class
 ical liquid scintillator detectors is the possibility of loading to unprec
 edented levels\, since high transparency is no longer required. I will giv
 e an overview of the LiquidO idea in this talk as well as show the first r
 esults from the ’micro-LiquidO’ prototype detector\, which provided th
 e proof of principle of light confinement.\n\nhttps://indico.tlabs.ac.za/e

DESCRIPTION:Speakers: Javier Menendez (University of Barcelona)\nNeutrinol
 ess double-beta decay (0nbb) is notoriously difficult to observe. Moreover
 \, expected decay rates depend on the value of the nuclear matrix elements
  (NMEs) which are poorly known. In order to obtain insights on the NMEs\, 
 and therefore on expected decay rates\, one can study other processes conn
 ected to 0nbb decay. In this talk I confront predictions and measurements 
 of the half-life and beta spectrum of the two-neutrino double-beta decays 
 to test nuclear models used to calculate 0nbb NMEs. In addition\, I discus
 s the relation between 0nbb NMEs (mediated by the weak interaction) and ot
 her nuclear observables such as double Gamow-Teller (strong) and double-ga
 mma\n(electromagnetic) transitions.\n\nhttps://indico.tlabs.ac.za/event/85

DESCRIPTION:Speakers: Alessandro Minotti (LAPP - IN2P3)\nThe SuperNEMO Exp
 eriment is designed to search for neutrinoless double beta decays of the S
 e-82 isotope. The detector employs the multi-observable tracking-and-calor
 imetry technique pioneered by the NEMO-3 Experiment.  Electrons originatin
 g from double beta decays of an isotope in thin isotopic foils are tracked
  in wire tracking chambers and their energy is measured by large scintilla
 tor blocks. The topology\,  timing\, and energy provide a powerful means o
 f identifying and measuring the final state of decays. The technique is al
 so very effective in rejecting backgrounds due mostly to traces of natural
  radioactivity in foils and detector materials. The SuperNEMO Demonstrator
  module is currently being commissioned at the Modane Underground Laborato
 ry in the Frejus Tunnel. We will discuss details of the detector elements\
 , the latest status of the experiment\, and the physics reach.\n\nhttps://

 d photon sensors to detect both thermal and scintillation signals produced
  by a particle interaction in the crystal to achieve high energy resolutio

DESCRIPTION:Speakers: Lotta Jokiniemi (University of Jyväskylä)\nTo desc
 ribe the double beta decay processes reliably one needs a possibility to t
 est the involved virtual transitions against experimental data. In this wo
 rk we manifest how to utilise\nthe nuclear and lepton ($\\mu$) charge-exca
 nge reaction data in the study of $0\\nu\\beta\\beta$ decay and astro-neut
 rinos. In my contribution I will cover the theoretical aspects of ordinary
  muon capture (OMC) as well as the recent studies of (3He\,t) and charge-e
 change studies at RCNP\, Osaka [1].\n\nThe OMC strength function in 100Nb 
 was computed in the pnQRPA framework [2]\, and compared with the experimen
 tal strength function measured at RCNP in Osaka [3]. The calculated first 
 OMC giant resonance in 100Nb is in agreement with the experimental value. 
 However\, the computed total OMC strength is higher than the measured stre
 ngth\, which refers to quenched g_A value.\nFurthermore\, the OMC rates to
  the daughter nuclei of the $0\\nu\\beta\\beta$ decay triplets of immediat
 e\nexperimental interest are computed [4] and compared with available data
  of [5].\nThe capture rates to the low-lying states of 76As are in accorda
 nce with the data. The OMC rates to\nthe daughter nuclei of $0\\nu\\beta\\
 beta$ decay triplets are also compared with the corresponding $0\\nu\\beta
 \\beta$\nmatrix elements in order to find possible connections between the
 m [6]. \n\nEventually\, the OMC process can be used to probe the structure
  of the intermediate states appearing in the\ndouble-beta-decay process. F
 uture experiments can help fine-tune the nuclear-structure parameters for 
 the\ndouble-beta-decay calculations.\n \n [1] H. Ejiri\, J. Suhonen\, and

 IBRA–phase2 experiment deep underground at Gran Sasso are presented\; th

 hold. The DAMA/LIBRA–phase2 data confirm the evidence of a signal that m
 eets all the requirements of the model independent Dark Matter annual modu

DESCRIPTION:Speakers: Ernesto Kemp (University of Campinas - UNICAMP)\nThe
  Deep Underground Neutrino Experiment (DUNE) is one of the most ambitious 
 particle physics experiments of the next generation. DUNE consists of two 
 detectors: the Near Detector (ND) - just downstream of the neutrino beam a
 t FERMILAB (IL - USA)\, and the Far Detector (FD) - 1300 km away and 1500 
 m deep in the underground SURF laboratory (SD - USA). The ND is a multi-te
 chnology apparatus aiming to constrain the uncertainties related to the un
 oscillated neutrino flux and also to explore neutrino interactions physics
 . The FD is a modular 40 kton fiducial mass Liquid Argon Time Projection C
 hamber\, dedicated to studying long-baseline neutrino oscillations\, which
  includes precise measurements of neutrino mixing parameters\, the CP viol
 ation phase as well as the determination of neutrino mass hierarchy. The p
 hysics list of DUNE extends to non-beam physics like supernova neutrinos a
 nd search for nucleon decay. In this contribution\, we describe the main f
 eatures of DUNE and its sensitivity for measurements on the primary physic
 s goals.\n\nhttps://indico.tlabs.ac.za/event/85/contributions/1503/

DESCRIPTION:Speakers: Kai Zuber (Technical University Dresden)\nThe lepton
  sector of the Standard Model is a very important and interesting field to
  search for new physics beyond the standard model. As we know that quarks 
 and neutrinos are mixing it is an open question why the charged leptons ar
 e now. This stimulates the search for charge lepton violation (CLFV). In a
 ddition\, neutrino-less double beta decay would violate total lepton numbe
 r by 2 and prove that neutrinos are their own antiparticle. The obtained h
 alf-life can be linked to a potential Majorana neutrino mass. This is prov
 iding a complementary measurement to normal beta decay where new interesti
 ng results are obtained.\nThis talk will shortly review the current situat
 ion in this area of research\, required support from theory and an outlook
  into the future.\n\nhttps://indico.tlabs.ac.za/event/85/contributions/151

 CHo) experiment is the determination of the electron neutrino mass by the 
 analysis of the electron capture spectrum of $^{163}$Ho. The detector tech
 nology is based on metallic magnetic calorimeters operated at a temperatur
 e of about 10 mK in a reduced background environment. For the first phase 
 of the experiment\, ECHo-1k\, the detector production has been optimized a
 nd the implantation process of high purity $^{163}$Ho source in large dete
 ctor arrays has been refined. The implanted detectors have been successful
 ly operated and characterized at low temperatures\, reaching an energy res
 olution below 5 eV. High statistics and high resolution $^{163}$Ho spectra
  have been acquired and analyzed in the light of the recent advanced theor
 etical description of the spectral shape\, considering the independently d
 etermined and more precise value of the energy available to the electron c
 apture process\, $Q_{\\rm EC}$. We present preliminary results obtained in
  ECHo-1k so far and discuss the necessary upgrades towards the second phas

DESCRIPTION:Speakers: Leendert Hayen (North Carolina State University & Tr
 iangle Universities Nuclear Laboratory)\nIt has been almost a decade since
  the reactor antineutrino anomaly entered the stage\, where the number of 
 experimentally detected antineutrinos emerging from a nuclear power reacto
 r interior was signicantly less than theoretically predicted from nuclear 
  decay. This has\, in turn\, motivated the search for an eV-scale sterile 
 neutrino in several very short baseline experiments\, none of which have s
 o far confirmed its existence. From the theory point of view\, initial ana
 lyses introduced a signicant number of approximations\, in particular for 
 the treatment of so-called forbidden transitions. We report on the first l
 arge-scale calculation of the influence of first-forbidden transitions usi
 ng state-of-the-art nuclear shell model calculations for a select number o
 f highly-contributing  branches. We use these results to propose a probabi
 lity distribution for first-forbidden spectral shapes and employ Monte Car
 lo techniques to translate this into a detailed construction of theoretica
 l uncertainties for the remaining forbidden transitions. We observed signi
 cant changes in both the integrated \nux and spectral shape of the cumulat
 ive antineutrino spectra spectra for all ssion actinides [1\, 2]\, and dis
 cuss both a mitigation of the so-called reactor shoulder and changes in th
 e reactor antineutrino anomaly. Finally\, we will comment how an improved 
 treatment of allowed  transitions [2\, 3] can further signicantly change b
 oth ux and spectral shape.\n[1] L. Hayen\, J. Kostensalo\, N. Severijns\,

DESCRIPTION:Speakers: Taka Kajino (Being University/NAOJ/University of Tok
 yo)\nThe big-bang universe\, supernovae (SNe)\, collapsars and binary neut
 ron-star mergers (NSMs) are the viable celestial sources of “multi-messe
 ngers”. These messengers are neutrinos for weak force\, gravitational wa
 ves for gravity\, photons for electromagnetism\, and atomic nuclei for str
 ong nuclear force [1]. Their detection takes the keys to solve still unans
 wered questions such as mass hierarchy of neutrinos [2]\, overproduction o
 f big-bang lithium [3]\, the origin of p-nuclei [4]\, and the origin of r-
 process elements [1\,5]. We will discuss the roles of neutrinos and radioa
 ctive nuclei for solving these problems.\nStill unknown neutrino mass and 
 oscillations are particularly important to answer the fundamental question
  why we need to go beyond the standard theory of elementary particles and 
 fields. We will\, first\, discuss cosmological background neutrinos and fl
 uctuations of primordial magnetic fields in order to solve overproduction 
 problem of primordial big-bang lithium [3]. The relic SN neutrinos also ar
 e the energetic component of cosmic background neutrinos. We will propose 
 a method how to constrain the neutrino mass hierarchy and EOS of proto-neu
 tron stars in the proposed HK project of detecting these energetic neutrin
 os [6].\nA huge flux of neutrinos is emitted from proto-neutron stars or a
 ccretion disks formed in SNe\, collapsars and binary NSMs. The collective 
 flavor oscillation due to the neutrino self-interactions is presumed to oc
 cur in the deepest region inside the iron-core\, while the MSW high-densit
 y resonance occurs near the bottom of He/C-layer. The light mass nuclei\, 
 7Li and 11B\, and the intermediate-to-heavy mass nuclei\, 19F\, 50V\, 53Mn
 \, 92Nb\, 98Tc\, 138La and 180Ta\, are respectively produced in outer He/C
 -layer and inner O-Ne-Mg-layer exposed to the intense neutrino flux (-p
 rocess) [2]. The intermediate mass p-nuclei\, 74Se\, 78Kr\, 84Sr\, 74Se\, 
 92\,94Mo and 96\,98Ru (p-process) [4]\, and r-process nuclei [1] are pr
 oduced in the iron-core. Therefore\, nucleosynthesis of 7Li and 11B is aff
 ected by both collective and MSW effects\, however all the other intermedi
 ate-to-heavy mass nuclei are affected by the collective oscillation alone\
 , being almost free from MSW effect. We will\, secondly\, discuss how diff
 erently these nucleosynthetic products depend on each of collective or MSW
  neutrino oscillation effect\, and will propose how to distinguish these t
 wo effects from each other [2].\nFinally\, we will discuss the origin of r
 -process nucleosynthesis to understand the cosmic evolutionary history of 
 each contribution from SN\, collapsar and binary NSM [5]. We here discuss 
 the roles of GW detection and spectroscopic astronomical observation of at
 omic nuclei as well as nuclear experiments of radioactive nuclei [1].\n\nh

DESCRIPTION:Speakers: Christian Weinheimer (Institut für Kernphysik\, Uni
 versity of Münster\, Germany)\nSince the discovery of neutrino oscillatio
 n we know that neutrinos have non-zero masses\, but we still do not know t
 he absolute neutrino mass scale\, which is as important for cosmology as f
 or particle physics. The direct search for a non-zero neutrino mass from e
 ndpoint spectra of weak decays is complementary to the search for neutrino
 less double beta-decay and analyses of cosmological data.\nToday the most 
 stringent direct limits on the neutrino mass originate from investigations
  of the electron energy spectra of tritium beta-decay.\n\nThe next generat
 ion experiment KATRIN\, the Karlsruhe Tritium Neutrino experiment\, is imp
 roving the sensitivity from the tritium beta decay experiments at Mainz an
 d Troitsk of 2 eV by one order of magnitude probing the region relevant fo
 r structure formation in the universe. KATRIN uses a strong windowless gas
 eous molecular tritium source combined with a huge MAC-E-Filter as electro
 n spectrometer. To achieve the sensitivity\, KATRIN has been putting many 
 technologies at their limits. The full 70m long setup has been successfull
 y commissioned. From early 2019 on KATRIN is taking high statistics tritiu
 m data hunting for the neutrino mass.\n\nIn this talk a detailed presentat
 ion of the KATRIN experiment and its results from the first KATRIN science
  run will be given. The new results are already bringing KATRIN into the l
 ead position of the field. In the outlook the perspectives of KATRIN for t
 he coming years and new technologies to potentially improve further the se
 nsitivity on the neutino mass will be presented.\n\nhttps://indico.tlabs.a

 Magurele\, Romania\n\nUntil the recent past not to much importance was giv
 en to the kinematic factors related to the double-beta decay\, i.e. the ph
 ase space factors\, electronic spectra and angular correlations between th
 e emitted electrons. The reason was largely because on the one side they w
 ere considered to be calculated/predicted with enough precision (in compar
 ison for example with the nuclear matrix elements) and\, on the other side
 \, the experimental measurements had not reached a sufficient degree of ac
 curacy to be able to distinguish fine details of them. This situation is c
 hanging now. A detailed analysis of the DBD electron spectra and angular c
 orrelations can provide us with useful information on transitions to excit
 ed states\, on decay modes and mechanisms contributing to neutrinoless DBD
  and\, very recently on possible effects of Lorentz symmetry violation in 
 the neutrino sector. \nIn my presentation I will give first a short review
  about the challenges in computation of the space phase factors\, electron
  spectra and electron angular correlations. Then\, I refer to the analysis
  of observable effects of Lorentz violation (LV) in two-neutrino DBD in th
 e framework of the Standard Model Extension (SME) and I present a comparis
 on between the methods of calculation the summed electron spectra includin
 g the deviations due to  LV associated to the like-time component of the s
 o-called countershaded operator.\nFinally\, I show that our predictions re
 garding electronic spectra correlated with their precise measurements that
  are currently being done in DBD experiments (like EXO-2000\, SuperNEMO\, 
 etc.) for searching LV effects\, can improve with up to 30% the actual upp
 er limits of the  (ä)3of  coefficient  that governs the LV contribution.

DESCRIPTION:Speakers: Alessio Caminata (INFN Genoa)\nThe Borexino liquid s
 cintillator neutrino observatory is devoted to perform high-precision neut
 rino observations: the study of solar neutrinos is the primary goal of the
  experiment. The exceptional radiopurity together with the good energy res
 olution (5% at 1 MeV) put Borexino in the unique situation of being able t
 o validate the MSW-LMA oscillation paradigm across the full solar energy r
 ange. A comprehensive study of  the pp-chain neutrinos was recently releas
 ed: this new study reports the direct measurements of pp\, 7Be and  pep ne
 utrino fluxes with the highest precision ever achieved (down to ~2.8% in t
 he 7Be component)\,  the 8B with the lowest energy threshold\, the best li
 mit on CNO neutrinos and the first Borexino limit on hep neutrinos. The pr

 d\, in particular\, on the more radiopure Phase-2 data\, taken after the d
 etector purification campaigns in 2010-11 and the perspectives for the fin

  mass number affects the information deduced from the possible future meas
 urements of the half-lives of neutrinoless double beta ($0\\nu\\beta\\beta
 $) decays [4]\,\nnuclear muon captures\, electron and antineutrino spectra
  of medium-mass fission fragments in nuclear reactors\, etc. In particular
 \, there could be direct effects on the reactor antineutrino anomaly and t
 he Gallium anomaly [1]. \n\nStudies of the $0\\nu\\beta\\beta$ decays of n
 uclei are of paramount importance in order to learn about the basic proper
 ties of the neutrino. An appealing way to probe this decay rather directly
  is the nuclear muon capture\, since it operates in the same momentum-exch
 ange region as the $0\\nu\\beta\\beta$ decays. Recent results on the muon 
 capture rate on $^{100}$Mo [5] indicate that the muon-capture calculations
  are able to reproduce the measured capture strength function in a quite s
 atisfactory way. \n\nIn my contribution I present an overview of the probl
 em of effective weak couplings and discuss the relation of the nuclear muo
 n capture to $0\\nu\\beta\\beta$ processes.\n\n*** REFERENCES ***

DESCRIPTION:Speakers: Clarence Virtue (Laurentian University / SNOLAB)\nHA
 LO-1kT is a lead-based supernova neutrino detector proposed for the Labora
 tori Nazionali del Gran Sasso (LNGS). By utilizing lead from the decommiss
 ioning of the OPERA detector at LNGS\, HALO-1kT will improve of the sensit
 ivity of the Helium and Lead Observatory (HALO)\, that has been running in
  SNOLAB in Canada for the past 7 years\, by a factor of ~25. The lead-base
 d neutrino detection technology takes advantage of the large neutrino-nucl
 ear cross sections for lead\, and Pauli-blocking of the anti-electron-neut
 rino charged current channel\, to offer a robust\, low cost and low mainte
 nance electron-neutrino-sensitive detector that complements water Cherenko
 v and liquid scintillator neutrino detectors. Neutrino detection is throug
 h charged and neutral current interactions with the lead nuclei that expel
  neutrinos that a subsequently detected with high efficiency in Helium-3 p
 roportional counters. The talk will focus on the physics capabilities of t
 he detector\; aspects of its design\; and its current status.\n\nhttps://i

DESCRIPTION:Speakers: Horst Lenske (U. Giessen)\nThe status and prospects 
 of heavy ion charge exchange reactions are discussed. Their important role
  for nuclear reaction\, nuclear structure\, and beta-decay investigations 
 is emphasized. Dealing with peripheral reactions\, direct reaction theory 
 gives at hand the proper methods for single (SCE) and double charge exchan
 ge (DCE) ion–ion scattering. The microscopic descriptions of charge exch
 ange ion–ion residual interactions and the reaction mechanism are obtain
 ed by distorted wave theory. Ion–Ion optical potentials and reaction for
 m factors are determined in a folding approach by using NN T-matrices and 
 microscopic ground state and transition densities\, respectively. The theo
 ry of onestep direct and two-step transfer reaction mechanisms for SCE rea
 ctions is discussed and illustrated in applications to data. Specific SCE 
 reactions are discussed in detail\, emphasizing the versatility of project
 ile–target combinations and incident energies. SCE reactions induced by 
 12C and 7Li beams are presented as representative examples. Heavy ion DCE 
 reactions are shown to proceed in principle either by sequential pair tran
 sfer or two kinds of collisional NN processes. Double single charge exchan
 ge (DSCE) is given by two consecutive SCE processes\, resembling in struct
 ure 2ν2β decay. A competing process is a two-nucleon mechanism\, relying
  on short range NN correlations and leading to the correlated exchange of 
 two charged mesons between projectile and target. These Majorana DCE (MDCE
 ) events are of a similar diagrammatic structure as 0ν2β decay. The simi
 larities of the DSCE and MDCE processes to pionic DCE reactions are elucid
 ated. An overview on recent applications to heavy ion DCE data is given.\n

 ure on nuclei\, dominate\, while all neutrino families are \nbeing produce
 d during the cooling phase of the protoneutron star.\n\nNeutrinos are cruc
 ial for the explosive nucleosynthesis. At first\, by \ninteraction with fr

 va simulations indicate that the ejected \nmatter is not sufficiently neut
 ron rich to support an r-process which also \nproduces the solar abundance
 s in the third r-process peak.\n\nNeutrino-induced spallation reactions on
  abundant nuclei in the outer\nstellar shells are responsible for the prod

DESCRIPTION:Speakers: Andrea Longhin ()\nThe knowledge of initial flux\, e
 nergy and flavor of current neutrino beams is currently the main limitatio
 n for a precise measurement of neutrino cross sections. The ENUBET ERC pro
 ject (2016-2021) is studying a facility based on a narrow band neutrino be
 am capable of constraining the neutrino fluxes normalization through the m
 onitoring of the associated charged leptons in an instrumented decay tunne
 l. Since March 2019\, ENUBET is also a CERN Neutrino Platform project (NP0
 6/ENUBET) developed in collaboration with CERN A&T and CERN-EN. In ENUBET\
 , the identification of large-angle positrons from $K_{e3}$ decays at sing
 le particle level can potentially reduce the $\\nu_e$ flux uncertainty at 
 the level of 1%. This setup would allow for an unprecedented measurement o
 f the $\\nu_e$ cross section at the GeV scale. Such an experimental input 
 would be highly beneficial to reduce the budget of systematic uncertaintie
 s in the next long baseline oscillation projects (i.e HyperK-DUNE). Furthe
 rmore\, in narrow-band beams\, the transverse position of the neutrino int
 eraction at the detector can be exploited to determine a priori with signi
 ficant precision the neutrino energy spectrum without relying on the final
  state reconstruction.\n\nThis contribution will present the final design 
 of the ENUBET demonstrator\, which has been selected on April 2019 on the 
 basis of the results of the 2016-2018 testbeams. It will also discuss adva
 nces in the design and simulation of the hadronic beam line. Special empha
 sis will be given to a static focusing system of secondary mesons that\, u
 nlike the other studied horn-based solution\, can be coupled to a slow ext
 raction proton scheme. The consequent reduction of particle rates and pile
 -up effects makes the determination of the $\\nu_{\\mu}$ flux through a di
 rect monitoring of muons after the hadron dump viable\, and paves the way 
 to a time-tagged neutrino beam. Time-coincidences among the lepton at the 
 source and the neutrino at the detector would enable an unprecedented puri
 ty and the possibility to reconstruct the neutrino kinematics at source on
  an event by event basis. We will also present the performance of positron
  tagger prototypes tested at CERN beamlines\, a full simulation of the pos
 itron reconstruction chain and the expected physics reach of ENUBET.\n\nht

DESCRIPTION:Speakers: Takaharu Otsuka (Department of Physics\, University 
 of Tokyo)\nThe neutrinoless double beta decay is of special importance in 
 determining the fundamental properties of neutrinos. The nuclear matrix el
 ement of this decay must be evaluated in a sufficient accuracy\, and the s
 hell-model calculation can make contributions to this end.  This is becaus
 e the shell-model calculations incorporate basically all correlations into
  the wave functions of the initial and final states of the decay\, and the
  accuracy of the calculation can be investigated by referring to other obs
 ervables.  I will report results obtained by recent large-scale shell-mode
 l calculations on 76Ge and 136Xe as well as their daughter nuclei 76Se and
  136Ba.   Here the large-scale shell-model calculations mean those by Mont
 e Carlo Shell Model at its most advanced edition.  The results are not awa
 y from the ranges of earlier studies\, but are rather on the edges of smal
 ler values.  I will also discuss why such smaller values arise as natural 
 consequences of basic features of the wave functions.\n\nhttps://indico.tl

DESCRIPTION:Speakers: Manuela Cavallaro (INFN - LNS)\nResearches on neutri
 noless double beta decay have crucial implications on particle physics\, c
 osmology and fundamental physics. It is likely the most promising process 
 to access the absolute neutrino mass scale. To determine quantitative info
 rmation from the possible measurement of the 0νββ decay half-lives\, th
 e knowledge of the Nuclear Matrix Elements (NME) involved in such transiti
 ons is mandatory. The use heavy-ion induced double charge exchange (DCE) r
 eactions as tools towards the determination of information on the NME is o
 ne of the goals of the NUMEN and the NURE projects. The basic point is tha
 t there are a number of similarities between the two processes\, mainly th
 at the initial and final state wave functions are the same and the transit
 ion operators are similar\, including in both cases a superposition of Fer
 mi\, Gamow-Teller and rank-two tensor components. \nThe availability of th
 e MAGNEX magnetic spectrometer for the measurements of the very suppressed
  DCE reaction channels is essential to obtain high resolution energy spect
 ra and accurate cross sections at forward angles including zero degree. Th
 e measurement of the competing multi-nucleon transfer processes allows to 
 study their contribution and to constrain the theoretical calculations. \n
 An experimental campaign is ongoing at INFN-Laboratori Nazionali del Sud (
 Italy) to explore medium-heavy ion induced reactions on target of interest
  for 0νββ decay. \nRecent results obtained by the (20Ne\,20O) and (18O\
 ,18Ne) DCE reactions and competing channels\, measured for the first time 
 using a 20Ne(10+) and 18O(8+) cyclotron beams at 15 AMeV will be presented
  at the conference.  A preliminary analysis of the double charge exchange 
 channel in comparison with the competitive multi-nucleon transfer channels
  will also be shown and commented.\n\nhttps://indico.tlabs.ac.za/event/85/
