TL;DR

This paper calculates the absorption cross sections of $B_c$ mesons by pions using a hadronic Lagrangian with SU(5) symmetry, providing data relevant for heavy ion collision studies.

Contribution

It presents the first calculation of $B_c$ absorption cross sections by pions using SU(5) hadronic Lagrangian including form factors.

Findings

Cross sections range from 2 to 7 mb for $B_c^+\pi \rightarrow DB$

Cross sections range from 0.2 to 2 mb for $B_c^+\pi \rightarrow D^*B^*$

Results are useful for $B_c$ production rate estimates in heavy ion collisions.

Abstract

The cross sections of $B_{c}$\ absorption by $\pi $ mesons are calculated using hadronic Lagrangian based on SU(5) flavor symmetry. Calculated cross sections are found to be in range 2 to 7 mb and 0.2 to 2 mb for the processes $B_{c}^{+}\pi \rightarrow DB$ and $B_{c}^{+}\pi \rightarrow D^{\ast}B^{\ast}$ respectively, when the monopole form factor is included. These results could be useful in calculating production rate of $B_{c}$ meson in relativistic heavy ion collisions.
