The ALICE experiment at the LHC is continuing its harvet of results from RUN1, while preparing for the second LHC RUN which will start next spring. In parallel, we are preparing for the long-term future, with a major upgrade to be installed during LS2 and which will allow a rich physics program in RUN3 and RUN4 of the LHC. The main items will be reviewed.

The nature of the 126 GeV Higgs recently discovered at CERN has not been established yet. One intriguing possibility is that it may arise as a light composite state from a confining dynamics at the TeV scale. I will review the recent progress in understanding the dynamics that may be behind this mechanism, focusing on what we can learn by knowing its details. The masses of the spin-1...

The search for directly produced DM particles exploits final states containing a high momentum object and missing transverse energy, such as monojet, monophoton, monolepton and monotop.
The production of DM particles...

We consider a model-independent and general framework to study the LHC phenomenology of vector-like quarks, including particles with different electro-magnetic charge. We consider vector-like quarks embedded in general representations of the weak SU(2)L, coupling to all Standard Model quarks via Yukawa mixing. We show that, with very minimal and quite general assumptions, they can be studied...

The production of hadrons, mainly of strange particles, has been studied intensively over the last decades as they are very powerful probes to study the dynamics of the high-density state created in heavy-ion collisions. With the new results from the LHC the energy range has been further extended and allows for a study of the various observables in a large energy range. Emphasis is put in...

The existing status of supersymmetry (SUSY) will be surveyed, with emphasis on the
LHC data. The main line of discussion will be: (a) a quick recapitulation of the
desirability of SUSY, (b) The viabiliy of testable supersymmetric scenarios in view
of current data, and (c) certain possibilities that are less emphasized in most discussions.

A distorted dispersion relation is derived for the lightest vector mesons ρ and ω and compared to the experimental results. The main characteristic of LPB is an invariant mass splitting that depends on the polarization. We present a detailed analysis of the...

Two-loop renormalization is introduced and discussed within the context of the Universal Extra-dimension (UED) models. Various issues will be discussed, in the minimal UED model, and its possible extensions to higher numbers of extra-dimensions and supersymmetry. An attempt will be made to define the running of the coupling constants at the two-loop level.

Low mass dileptons are powerful tools to study the evolution of the system created in relativistic heavy ion collisions because (i) they are produced in all stages the collision, and (ii) they do not interact strongly thus leave the collision area unaffected by the final state interactions. Low mass dileptons provide also an ideal way to access the thermal photon radiation from the hot and...

Even if the unification and supersymmetry breaking scales are around $10^6$ to $10^9$ TeV, a large $A_t$ coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details of supersymmetry breaking, we take advantage of power law running in five dimensions and a compactification scale in the 10 − $10^3$ TeV range to show how the gluino...

Direct-photons produced in the hot fireball of a heavy-ion collision leave the medium unscathed. They are therefore believed to provide information about the very early stage of the collisions. In particular, the direct photon pT spectrum at low pT (1 < pT < 4 GeV/c) might contain information about the initial temperature of the quark-gluon plasma. A further diagnostic tool is the azimuthal...

The LHC has run p-Pb collisions at √s_{NN} = 5.02 TeV in addition to √s_{NN} = 2.76 TeV Pb-Pb and the pp physics program. The p-Pb program was conceived originally to investigate initial-state effects in the collisions of nuclei. The p-Pb results appear to exhibit a lack of strong initial-state effects, but are surprising in that they reveal a strong similarity to the final-state hydrodynamic...
