Decay properties of charm and beauty open flavour mesons

摘要

The masses of S and P states, pseudoscalar and vector decay constants, leptonic, semileptonic decay widths of charm (D) and beauty (B) open flavour mesons have been computed in the framework of Coulomb and power potential of the form V(r) = ?a_c/r+Ar~v. The results are compared with other theoretical as well as experimental results.
