Towards two- and three-loop QCD corrections to the width difference in $B_s-\bar{B}_s$ mixing
In this work we address the issue of large perturbative uncertainties in the theory prediction for $\Delta \Gamma_s$, the width difference in the $B^0_s - \bar{B}^0_s$ mixing process. To this aim we complete important steps towards the full analytic result for the previously unknown Wilson coeffi...
