| contents | This report summarises recent advances made in the calculation of the NNLO QCD corrections to the width difference $ΔΓ_s$ in the $B_s-\overline{B}_s$ system. The inclusion of the effects due to current-current operators leads to an updated prediction of $ΔΓ_s = (0.076\pm 0.017)\,\text{ps}^{-1}$, which narrows the gap between theory and experiment. |
