# Minimal unified resolution to $R_{K^{(*)}}$ and $R(D^{(*)})$ anomalies with lepton mixing

## TL;DR

This paper proposes a minimal effective theory with two parameters that can simultaneously explain anomalies in B-meson decay ratios $R_K$, $R_{K^*}$, $R(D)$, and $R(D^*)$, and predicts testable signatures in B decays and high-energy collisions.

## Contribution

It introduces a simple, unified effective theory with only two parameters that accounts for multiple B-meson decay anomalies and predicts observable signatures.

## Key findings

- Successfully explains $R_K$, $R_{K^*}$, $R(D)$, and $R(D^*)$ anomalies with minimal parameters.
- Predicts distinctive signatures in B decays and collider experiments.
- Provides a compelling new physics scenario consistent with current data.

## Abstract

It is a challenging task to explain, in terms of a simple and compelling new physics scenario, the intriguing discrepancies between the standard model expectations and the data for the neutral-current observables $R_K$ and $R_{K^*}$, as well as the charged-current observables $R(D)$ and $R(D^*)$. We show that this can be achieved in an effective theory with only two unknown parameters. In addition, this class of models predicts some interesting signatures in the context of both $B$ decays as well as high-energy collisions.
