Description

In the current work, We calculate the heavy quark (charm and bottom) energy loss due to elastic collisions and gluon radiation in proton-Lead (pPb) collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV. We use the Peigne and Peshier formalism to calculate the collisional energy loss and generalised dead cone approach and DGLV formalism to calculate the radiative energy loss. We also calculate the fluctuations.
Nuclear modification factors including shadowing, energy loss and fluctuations are calculated for $B$ and $D$ mesons in pPb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV and are compared with the measured CMS and ALICE data.
