τBs/τBd and ΔΤs confront new physics in b → sττ
Several new physics scenarios that address anomalies in B-physics predict an enhancement of b → sττ with respect to its Standard Model prediction. Such scenarios necessarily imply modifications of the lifetime ratio τBs/τBd andthe lifetime difference ΔΤs. In this work, we explore indirect bounds provided by these observables over new physics scenarios. We also estimate future projections, showing that future experimental and theoretical improvements on bothτBs/τBd and ΔΤs have the potential to provide bounds competitive with those directly extracted from b → sτ τ transitions. After performing a model-independent analysis, we apply our results to the particular case of leptoquark mediators proposed to address the RD(∗) anomalies.

Abstract
Several new physics scenarios that address anomalies in B-physics predict an enhancement of b → sττ with respect to its Standard Model prediction. Such scenarios necessarily imply modifications of the lifetime ratio τBs/τBd andthe lifetime difference ΔΤs. In this work, we explore indirect bounds provided by these observables over new physics scenarios. We also estimate future projections, showing that future experimental and theoretical improvements on bothτBs/τBd and ΔΤs have the potential to provide bounds competitive with those directly extracted from b → sτ τ transitions. After performing a model-independent analysis, we apply our results to the particular case of leptoquark mediators proposed to address the RD(∗) anomalies.
