Thermal Charm Production in Quark-Gluon Plasma at LHC

Abstract

Charm production from the quark-gluon plasma created in the midrapidity of central heavy ion collisions at the Large Hadron Collider (LHC) is studied in the next-to-leading order in QCD. Using a schematic longitudinally boost-invariant and transversally expanding fire-cylinder model, we find that charm production could be appreciably enhanced at LHC as a result of the high temperature that is expected to be reached in the produced quark-gluon plasma. Sensitivities of our results to the number of charm quark pairs produced from initial hard scattering, the initial thermalization time and temperature of the quark-gluon plasma, and the charm quark mass are also studied.

8 pages, 9 figures; adding a figure and relevant discussion on the sensitivity of our results to the number of charm quark pairs produced from initial hard scattering. Version accepted for publication in PRC
