Decay constants, semi-leptonic and non-leptonic decays in a Bethe-Salpeter Model

A. Abd El-Hady, Alakabha Datta, J. P. Vary

We evaluate the decay constants for the B and $D$ mesons and the form factors for the semileptonic decays of the B meson to $D$ and $D^{\ast }$ mesons in a Bethe-Salpeter model. From dat…
