Interactions of $B_c$ Meson in Relativistic Heavy-Ion Collisions

Abstract

We calculate the absorbtion cross-sections of $B_c$ mesons by $\pi$ and $\rho$ mesons including anomalous processes using an effective hadronic Lagrangian. The enhancement of Bc production is expected due to QGP formation in heavy-ion experiments. However it is also expected that the production rate of Bc meson can be affected due to the interaction with comovers. These processes are relevant for experiments at RHIC. Thermal average cross-sections of $B_c$ are evaluated with form factor when a cut off parameter in it is 1 and 2 GeV. Using these thermal average cross-sections in the kinetic equation we investigate the time evolution of $B_c$ mesons due to dissociation in the hadronic matter formed at RHIC.
