The $B_c$ decay rate in the Standard Model

High Energy Physics - Phenomenology 2022-04-14 v1

Abstract

The Standard Model decay rate of the BcB_c meson is discussed together with a novel approach based on the usage of experimental data in combination with an operator product expansion. In the new method differences of B,DB,\,D and BcB_c meson decay rates are considered, for which the free-quark contributions drop out, leading to a reduction of the theory prediction.
