Precision Study of Semileptonic and Non-Leptonic $B_{c}$ Decays to $I^\cdot_{c}$ and P Wave Charmonia

Aritra Biswas, Soumitra Nandi, Shantanu Sahoo

We analyse semileptonic and non-leptonic decays of the $B_{c}$ meson into P wave charmonium states. The analytic expressions for the transition form factors are taken from NRQCD, whi…
