Abstract

Measurements of inclusive spectra and mean multiplicities of $$\pi ^\pm $$ π&#177; , K$$^\pm $$ &#177; , p and $${\bar{\text {p}}}$$ p&#175; produced in inelastic p + p interactions at incident projectile momenta of 20, 31, 40, 80 and 158 $$\text{ GeV }/c$$ GeV/c ($$\sqrt{s} = $$ s= 6.3, 7.7, 8.8, 12.3 and 17.3 $$\text{ GeV }$$ GeV , respectively) were performed at the CERN Super Proton Synchrotron using the large acceptance NA61/SHINE hadron spectrometer. Spectra are presented as function of rapidity and transverse momentum and are compared to predictions of current models. The measurements serve as the baseline in the NA61/SHINE study of the properties of the onset of deconfinement and search for the critical point of strongly interacting matter.
