Hadron Production at Intermediate $p_T$ at RHIC

Abstract

Large proton and antiproton enhancement with respect to pions has been observed at intermediate transverse momentum $p_T\approx$ 2-5 GeV/$c$ in Au+Au collisions at RHIC. To investigate the possible source of this anomaly, the production of $\varphi$ mesons and two particle angular correlations triggered by mid-$p_T$ baryons or mesons are studied. We also present the first measurement of proton and antiproton production at $\sqrt{s_{NN}}=62.4$ GeV in Au+Au collisions, which aims to study the energy dependence of the observed baryon enhancement.
