Description
We report on the calculation of the previously unknown 2- and 3-loop QCD corrections to the flavor precision observable $\Delta \Gamma_{12}^s$ that arises in the mixing of neutral $B_s$ mesons. This project is a crucial step towards the task of reducing the existing perturbative uncertainties of this observable which happen to be much larger than the current experimental error.
