- Abstract: The transverse momentum (pT ) spectra and ratios of identified charged hadrons (π ±, K±, p, p¯) produced in √sNN = 200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to pT = 6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to pT = 4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate pT region, between 2–5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The pT dependent particle ratios for these classes display a remarkable similarity, which is then discussed
