Radiative Energy-Loss of Heavy Quarks in a Quark-Gluon Plasma

摘要

We estimate the radiative energy-loss of heavy quarks, produced from theinitial fusion of partons, while propagating in a quark-gluon plasma which maybe formed in the wake of relativistic heavy ion collisions. We find that theradiative energy-loss for heavy quarks is larger than the collisionalenergy-loss for all energies. We point out the consequences on possible signalsof the quark-gluon plasma.
