 Spectator induced electromagnetic effects on charged meson production in nucleus-nucleus collisions from NA61/SHINE at CERN SPS / Bhosale, Sneha (Cracow, INP) /NA61/SHINE Collaboration The SPS Heavy Ion and Neutrino Experiment (NA61/SHINE) studies the properties of hadron emission in collisions of beams of hadrons and nuclei with fixed hadronic and nuclear targets. In recent years, the NA61/SHINE physics program has been supplemented with studies of electromagnetic (EM) effects, induced by the spectator charge on spectra and ratios of emitted charged mesons.

 Hadron Production Measurements for Improving Neutrino Flux Predictions With the NA61/SHINE Spectrometer / Ilieva, Simona (Sofiya U.) /NA61/SHINE Collaboration In neutrino experiments the dominant contribution to the total uncertainty of the neutrino flux comes from the modeling of hadron interactions. Thus, hadron production measurements are necessary to better constrain the neutrino beam.

 Multi-strange hadron production in p+p interactions at $\sqrt{s_{NN}}$ = 17.3 GeV / Pulawski, Szymon (Silesia U.) /NA61/SHINE Collaboration The production of multi-strange hadrons in proton-proton interactions is currently studied with the NA61/SHINE experiment at the SPS. These particles are reconstructed via their weak decay typologies, exploiting the tracking and particle identification capabilities of NA61/SHINE.

 Fluctuations and Correlations Study at NA61/SHINE / Prokhorova, D (St. Petersburg State U.) /NA61/SHINE Collaboration The strong interactions program of NA61/SHINE, a fixed-target experiment at the CERN SPS, focuses on the search for the critical point of strongly interacting matter. The strategy of the collaboration is to perform a comprehensive two-dimensional scan of the phase diagram μ B – T by changing the collision energy and the system size.

 Particle Production Properties at SPS Energy Range — Recent Results from the NA61/SHINE Experiment / Pulawski, Sz (Silesia U.) ; Kowalski, S (Silesia U.) One of the main physics goals of the NA61/SHINE programme on strong interactions is the study of the properties of the onset of deconfinement. This goal is pursued by performing an energy- (beam momentum 13A–158A GeV/c) and system-size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. In particular, recent inclusive spectra of identified hadrons in inelastic p+p and centrality selected Be+Be and Ar+Sc interactions at the SPS energies. [...] 2021 - 5 p. - Published in : Acta Phys.

 Synergy in the Development of Forward Hadron Calorimeters for NA61/SHINE, BM@N, MPD and CBM Experiments / Guber, F (Moscow, INR ; Moscow, MIPT) ; Golubeva, M (Moscow, INR) ; Ivashkin, A (Moscow, INR ; Moscow, MIPT) ; Karpushkin, N (Moscow, INR ; Moscow, MIPT) ; Morozov, S (Moscow, INR ; Moscow Phys. Eng. Inst.) The lead/scintillator transverse and longitudinal segmented forward hadron calorimeters will be used in the upgraded BM@N and NA61 experiments and future CBM and MPD experiments to measure centrality and reaction plane orientation in heavy-ion collisions. Common tasks in development of forward hadron calorimeters for these experiments, including development of different approaches of the centrality determination, signals treatment, energy calibration procedure are discussed.. 2021 - 4 p. - Published in : Acta Phys.

 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.. 2020 - 7 p. - Published in : PoS ICRC2019 (2020) 061 Fulltext: PDF; In : 36th International Cosmic Ray Conference, Madison, WI, USA, 24 Jul - 1 Aug 2019, pp.061
