Abstract

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