Description
NA61/SHINE is an experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are the search for the critical point of strongly interacting matter and study the properties of the onset of deconfinement. In order to reach these goals, the two-dimensional scan in beam momentum (13A-150A GeV/c) and system size (p+p, Be+Be, Ar+Sc, Xe+La, Pb+Pb) was performed.
In the final stage of the collision, when resonance decays and re-scattering are important, the spectra of protons are not as affected as of pions, due to the large difference in mass. Thus, proton rapidity distribution is especially sensitive to the onset of deconfinement.
This contribution presents experimental results on proton production relevant for the onset of deconfinement. Experimental techniques and methods used to analyse hadrons will be reviewed. Examples of transverse momentum and rapidity spectra will be also shown. Moreover, a comparison with the existing data will be given.
