Abstract
The standard model assumes that the three charged leptons, namely electrons e, muons μ, and taus τ , have an identical electroweak coupling, and the distinction arises from their different masses. Several independent experiments, including BaBar, Belle, and LHCb, have found deviations from SM predictions. Some of these anomalies arises in the b → cν transition, referred to as charged anomalies. Recent measurements have been reported with the purpose of addressing these anomalies, a brief overview of these results is provided. It is worth noting that the overall tension between theoretical predictions based on the Standard Model and the world average including these new measurements remains at the 3σ level.
