The effects of heavy quarks energy loss on the transverse momentum spectra of single muons are studied. The energy loss of heavy quarks when traversing the medium formed in PbPb collisions at √sNN = 5.5 TeV is calculated by implementing the collision geometry and the quenching weights. The medium density is assumed to decrease at forward pseudo-rapidity and to be proportional with pseudo-rapidity multiplicity dN/dη. Muons from W decays can be used as a medium-blind reference to quantify the effect of heavy quarks energy loss o...
