Some of semileptonic and nonleptonic decays of $B_c$ meson in a Bethe-Salpeter relativistic quark model

Chao-Hsi Chang, Hui-Feng Fu, Guo-Li Wang +1

The semileptonic decays $B_c^{+}\to P(V)+{\ell }^{+}+{\bar{\nu }}_{\ell }$ and the nonleptonic decays $B_c^{+}\to P(V)+L$, where $P(V)$ denotes a pseudoscalar (vector) charmonium or…
