    Hadronic Physics

    A non-monotonic net-proton kurtosis as a function of the collision
    energy for very central collisions has been suggested and may be
    confirmed by recent BES-II program results advocating the existence of
    the QCD critical point. Fluctuations at the origin of this peculiar
    behavior are produced in the highly dynamic environment of
    ultra-relativistic collisions. Especially, the violent...

    The High Acceptance Di-Electron Spectrometer (HADES) at GSI, Darmstadt,Germany is an experimental setup dedicated to study the hadronic matter in the region of large net baryon densities and moderate temperatures, using fixed-target heavy-ion collisions in the incident energy range of few GeV/nucleon. Dilepton emission is a favored probe for such studies as it gives undistorted information...

    Hadronic Physics

    Symmetries play a crucial role in our current understanding of the fundamental properties of the Universe. Any combination of the three discrete operations, i.e. charge conjugation (C), parity (P), and time reversal (T) results in a CPT transformation. The corresponding CPT theorem states that CPT is an exact symmetry of nature and puts the following constraints on any quantum field theory...

    Charged-particle pseudorapidity measurements help in understanding particle production mechanisms in high-energy hadronic collisions, from proton-proton to heavy-ion systems. Performing such measurements at forward rapidity, in particular, allows one to access the details of the phenomena associated with particle production in the fragmentation region. In ALICE, this measurement will be...

    Hadronic Physics

    The presence of an unexpected significant excess of low $p_{T}$ $J/\psi$ over the expected hadronic $J/\psi$ production was confirmed in peripheral Pb$-$Pb collisions and observed for the first time in semi-central Pb$-$Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with ALICE at LHC. The measurements were performed in the dimuon decay channel at forward rapidity ($2.5 < y < 4$) and in the...
