τBc in the Standard Model
Published on:
November 23, 2022
Abstract
The Standard Model prediction of the Bc lifetime is discussed, together with the dominant uncertainties and strategies on how to improve them. Furthermore, a new method to compute the Bc lifetime based on the operator product expansion is proposed. It relies on differences of B,D and Bc meson decay rates, in which the free-quark contributions cancel out, reducing the uncertainty of the theory prediction.
