abstract
B_c meson production in Pb+Pb collisions at sqrt{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.

Nuclear modification of $B_c$ mesons in relativistic heavy-ion collisions based on a linear Boltzmann transport model
A linear Boltzmann transport model with Yukawa and string interactions reproduces the measured B_c nuclear modification in Pb+Pb collisions and predicts larger low-pT B_c R_AA in Au+Au at RHIC than at the LHC.
