摘要：

The enhancement of B-c production is expected due to formation of quark-gluon plasma in heavyion collisions. However, it is also expected that the production rate of B-c meson can be affected by its interactions with comovers in hot hadronic gas. To study this effect we calculate the dissociation cross sections of B-c meson by n and p mesons, including anomalous processes using an effective hadronic Lagrangian. Thermal averaged cross sections of B-c are evaluated with a form factor when a cutoff parameter in it is 1 and 2 GeV. Using these cross sections in the kinetic equation, we study the time evolution of B-c mesons in hot hadronic matter formed at LHC. We find that the effect of interactions with comovers is small but not negligible.
