Abstract
The production of heavy quarks in heavy-ion collisions is important because it is expected to give information about high-density QCD matter. One interesting channel of heavy quark measurements at LHC is the decay of B to J/ψ. The J/ψ mesons from this channel can be separated from the primary J/ψ (produced at collision vertex) by using the secondary vertex which is efficiently reconstructed with the CMS tracker. In this work, the generator level results for the primary and secondary J/ψ obtained through dimuon pairs are presented for pp and PbPb collisions at \( \sqrt {s_{NN} } \) = 5.5 TeV.
