DESCRIPTION:Speakers: Liangjian Wen (Institute of High Energy Physics\, Be
 ijing\, China)\nIt is extremely important for future neutrinoless double-b
 eta ($0\\nu\\beta\\beta$) decay experiments to reach a sensitivity to effe
 ctive Majorana neutrino mass $|m_{\\beta\\beta}|$~meV. At this level\, the
  determination of neutrinos’ Majorana nature\, absolute masses and the c
 onstraints on one of two Majorana CP phases are possible\, which will prov
 ide profound insights into understanding the neutrino mass origin and the 
 observed matter-antimatter asymmetry in our Universe. The Jiangmen Undergr
 ound Neutrino Observatory (JUNO)\, which has the largest liquid scintillat
 or (LS) detector with extremely low background and excellent energy resolu
 tion\, will be online soon. JUNO has great potential to be upgraded to sea
 rch for $0\\nu\\beta\\beta$ and to reach a sensitivity of $|m_{\\beta\\bet
 a}|$~meV after its primary mission on the determination of neutrino mass o
 rdering and the precision measurements of oscillation parameters is accomp
 lished. The dedicated R&D program focused on the LS doping with a suitable
  $0\\nu\\beta\\beta$-decaying isotope and the purification\, as well as on
  the development of advanced techniques for background rejection\, are bei
 ng carried out in the past and forthcoming years. If successful\, JUNO cou
 ld be ready to begin searching for $0\\nu\\beta\\beta$ decays at the turn 
 of the next decade. This talk will report the up-to-date R&D progresses on
  Tellurium-doped LS development and the studies on the cosmogenic backgrou
 nds on Tellurium.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/29
