Dimuon production from heavy quark decay in heavy-ion collisions at root s=5.5 TeV

The production of heavy-flavor quark c((c) over bar) and b((b) over bar) in pp collisions is described under perturbative quantum chromodynamics frame work, the extrapolation from hadron-hadron up to nucleus-nucleus collisions Is based on geometrical model by taking into account the nucleus shadowing effect. We simulate the heavy quark production, the decay to dilepton and effects of detection and analysis technique of the pairs, and predict the m uon rate and the invariant mass spectrum of dimuons that could be detected in forward region in Pb-Pb collisions at large hadron collider energies.
