Effect of Energy Loss On Azimuthal Correlation of charm and correlated charm decay in collision of lead nuclei at sqrt{s} = 2.76 A TeV

Abstract

We present the effect of energy loss of charm/anti-charm produced in a relativistic heavy ion collision as they traverse the resulting quark gluon plasma on the azimuthal correlation of c\bar{c} and D\bar{D} pairs and their correlated decay into leptons. We employ an empirical model of energy loss by charm quark energy loss and find that the consequences are easily discernible as different cuts on their momenta are applied. We also notice a modest increase in the invariant mass spectrum of dileptons from correlated decay as mentioned above due to energy loss.
