Title: Identified Hadron Compositions in p+p and Au+Au Collisions at High Transverse Momenta at √(sNN)=200 GeV

Abstract

We report transverse momentum (pT≤15 GeV/c) spectra of π±, K±, p, p̄, K0S, and ρ⁰ at midrapidity in p+p and Au+Au collisions at √(sNN)=200 GeV. Perturbative QCD calculations are consistent with π± spectra in p+p collisions but do not reproduce K and p(p̄) spectra. The observed decreasing antiparticle-to-particle ratios with increasing pT provide experimental evidence for varying quark and gluon jet contributions to high-pT hadron yields. The relative hadron abundances in Au+Au at pT ≳ 8 GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.

abstractNote = {We report transverse momentum (pT≤15 GeV/c) spectra of π±, K±, p, p̄, K0S, and ρ⁰ at midrapidity in p+p and Au+Au collisions at √(sNN)=200 GeV. Perturbative QCD calculations are consistent with π± spectra in p+p collisions but do not reproduce K and p(p̄) spectra. The observed decreasing antiparticle-to-particle ratios with increasing pT provide experimental evidence for varying quark and gluon jet contributions to high-pT hadron yields. The relative hadron abundances in Au+Au at pT ≳ 8 GeV/c are measured to be similar to the p+p results, despite the expected Casimir effect for parton energy loss.},
