Recent measurements of identified hadron spectra and multiplicities in Ar+Sc and Be+Be collisions at SPS energies
2019 September 19
NA61/SHINE is a fixed target experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are to discover the critical point of strongly interacting matter and to study the properties of the onset of deconfinement. In order to reach these goals, a study of hadron production properties is performed in nucleus-nucleus, proton-proton and proton-nucleus interactions as a function of collision energy and size of the colliding nuclei. In this talk, the newest preliminary results on identified hadron spectra produced in Ar+Sc and Be+Be collisions at six beam momenta (13$A$, 19$A$, 30$A$, 40$A$, 75$A$ and 150$A$ GeV/$c$}) will be shown. The kinematic distributions and measured multiplicities of identified hadrons will be compared with NA61/SHINE and NA49 p+p and Pb+Pb results, as well as with available world data.
