Description
In recent times, several hints of lepton flavour universality violation have been observed in semileptonic B decays at the level of (2 − 4)σ, both in the rare flavour changing neutral current (NC) transitions b → sll and charged current (CC) transitions b → clν . These tantalizing signals point towards the possible existence of New Physics beyond the Standard Model. Numerous studies have been performed to understand these anomalies in various new physics models as well as in model-independent approaches. Since the new physics scales involved in the CC and NC sectors are significantly different from each other, explanation of these intriguing sets of discrepancies in a coherent manner using a single framework is rather challenging. We will discuss a few such scenarios which could successfully illustrate all these anomalies and their implications on the Invisible sector.
