# Revisiting Minimal Lepton Flavour Violation in the Light of Leptonic CP Violation

## TL;DR

This paper re-evaluates the Minimal Lepton Flavour Violation framework in light of recent CP violation evidence, analyzing different scenarios and their experimental implications, and critically assesses its ability to explain B-meson decay anomalies.

## Contribution

It provides a detailed analysis of MLFV scenarios considering recent CP violation data and discusses their compatibility with leptonic decay constraints and B-meson anomalies.

## Key findings

- Degenerate right-handed neutrino scenario is disfavoured by CP violation evidence.
- Predictions for leptonic rare decays help distinguish MLFV scenarios.
- B-meson decay anomalies cannot be explained within MLFV without conflicting with leptonic bounds.

## Abstract

The Minimal Lepton Flavour Violation (MLFV) framework is discussed after the recent indication for CP violation in the leptonic sector. Among the three distinct versions of MLFV, the one with degenerate right-handed neutrinos will be disfavoured, if this indication is confirmed. The predictions for leptonic radiative rare decays and muon conversion in nuclei are analysed, identifying strategies to disentangle the different MLFV scenarios. The claim that the present anomalies in the semi-leptonic $B$-meson decays can be explained within the MLFV context is critically re-examined concluding that such an explanation is not compatible with the present bounds from purely leptonic processes.
