    Abstract

    Measurements of the transverse momentum spectra of charged pions and anti-protons produced in pAu collisions at at 200 GeV are presented. The data were collected by the PHENIX experiment in 2015. The pion and anti-proton spectra, the anti-proton/negative pion ratio, and the nuclear modification factors, RpAu, are obtained in several different centrality classes: 0-20%, 20-40%,40-60%,60-84%, and 0-100% using a minimum bias trigger, and in 0-5% - using a high-multiplicity trigger. At low pT (< 1.5 GeV) the spectral shapes and the anti-proton/negative pion ratio are well described by hydrodynamics calculations. In central collisions for hadrons with pT > 1.5 GeV, the anti-proton/negative pion ratio is enhanced compared to the ratio in proton-proton collisions, and RpAu for anti-protons is above unity. These enhancements are similar to those observed in d+Au collisions with similar number of participating nucleons.
