B_c meson enhancement and the momentum dependence in Pb+Pb collisions at LHC energy

B-c meson production in Pb + Pb collisions at root s = 2.76 A TeV is surveyed in both a statistical coalescence model and a transport model. The nuclear modification factor R-AA is predicted to be between 2 and 18 in the most central collisions, which can help to confirm the regeneration mechanism. In addition, the momentum dependence is also investigated as given by the transport model. A strong suppression of the transverse momentum is found in central collisions accompanying the enhancement in yield. The spectrum and elliptic flow of B-c are also discussed.
