Abstract

Average energy loss of light quarks has been calculated in a two stage equilibrium scenario where the quarks are executing Brownian motion in a gluonic heat bath. The evolution of the quark p_T spectra is studied by solving Fokker-Planck equation in an expanding plasma. Results are finally compared with experimentally measured pion p_T spectrum at RHIC.
