$\tau _{B_{s}}/\tau _{B_{d}}$ and $\Delta \Gamma _{s}$ confront new physics in $b\rightarrow s\tau \tau $
Several new physics scenarios that address anomalies in B-physics predict an enhancement of $b \rightarrow s \tau \tau $ with respect to its Standard Model prediction. Such scenarios necessarily imply modifications of the lifetime ratio $\tau _{B_{s}}/\tau _{B_{d}}$ and the lifetime difference $\Del...
