Description
In this talk I will report on the calculation of NNLO QCD corrections to the
flavor observables in the mixing of neutral $B$ mesons and discuss their
numerical impact. The physical relevance of this work stems from the fact
that experimental measurements of e.g. the flavor mixing parameter
$\Delta \Gamma_{12}^s$ have already achieved per cent level accuracy,
while theoretical predictions are still affected by large uncertainties
from uncalculated perturbative corrections. My presentation will be based
on our recent publications arXiv:2106.05979 and arXiv:2202.12305.
