Production cross sections of cosmic antiprotons in the light of new data from the NA61 and LHCb experiments / Donato, Fiorenza (Turin U. ; INFN, Turin) ; Korsmeier, Michael (Turin U. ; INFN, Turin ; Aachen, Tech. Hochsch.) ; di Mauro, Mattia (NASA, Goddard ; Catholic U.)
The cosmic-ray flux of antiprotons is measured with unprecedented precision by the particle spectrometer AMS-02 on the International Space Station.Its interpretation requires a correct description of the dominant production process for antiprotons in our Galaxy, namely, the interaction of cosmic-ray proton and helium with the atoms of the interstellar medium.In light of new cross section measurements by the NA61 experiment of $p$ + $p$ $\rightarrow$ $\bar{p}$ + $X$ and the first ever measurement of $p$ + He $\rightarrow$ $\bar{p}$ + $X$ by the LHCb experiment in a fixed target configuration, we update the parametrization of proton-proton and proton-nucleon cross sections and their uncertainties.The new parametrizations for the cross section are used to derive the total source term of secondary antiprotons. Since uncertainties, in particular at low energies, are significantly larger than those on the measured antiproton fluxby the AMS-02 experiment, we finally quantify the necessity of new data on antiproton production cross sections, and pin down the kinematic parameter space which should be covered by future high-energy experiments..

Open charm measurements at CERN SPS energies in the NA61/SHINE experiment - status and plans / Merzlaya, Anastasia (St. Petersburg State U.) /Na61/Shine Collaboration
The study of open charm meson production provides an efficient tool for detailed investigations of the properties of hot and dense matter formed in nucleus-nucleus collisions. In particular, charm mesons are of vivid interest in the context of the phase-transition between confined hadronic matter and the quark-gluon plasma. [...]

Recent results from proton intermittency analysis in nucleus-nucleus collisions from NA61/SHINE at CERN SPS / Davis, Nikolaos (Cracow, INP) ; Antoniou, Nikolaos (Athens U.) ; Diakonos, Fotios K (Athens U.) /Na61/Shine Collaboration
The search for experimental signatures of the critical point (CP) of strongly interacting matter is one of the main objectives of the NA61/SHINE experiment at CERN SPS. In the course of the experiment, an energy (beam momentum 13A - 150A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan is performed. [...]
