Nuclear modification and azimuthal anisotropy of D mesons produced in relativistic heavy ion collision

In this paper we present a phenomenological treatment of charm quark energy loss before fragmenting into D mesons and calculate nuclear modification factor, ‘$R_{AA}$’ and azimuthal anisotropy, ‘$v_2$’ of D mesons for lead on lead collision at LHC energy of $\sqrt{s}$=2.76 A TeV.
