Abstract: 

The cross sections of Bc absorption by baryons (nucleons) and mesons (pi, rho, kaon) are calculated in meson–baryon exchange model using hadronic Lagrangian based on SU(4)/SU(5) flavor symmetries. The values of different coupling constants used in the model are obtained from vector meson dominance model, QCD sum rule or SU(4)/SU(5) flavor symmetries. Calculated values of cross sections are found to be significant. These results could be useful in calculating production rate of Bc meson in relativistic heavy ion collisions.
