摘要：
Transverse momentum spectra of pions, protons, and antiprotons in Au+Au collisions at intermediate RHIC energy root s(NN)=62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter and fragmentation of the quenched perturbative minijet partons. The resulting baryon to meson ratio at intermediate transverse momenta is predicted to be larger than that seen in experiments at higher center of mass energies.
