# Rank-One Flavor Violation and B-meson anomalies

## TL;DR

This paper proposes a rank-one flavor violation model for B-meson anomalies, linking observed anomalies to other flavor and high-energy observables, and predicts that upcoming experiments will explore much of its parameter space.

## Contribution

It introduces a rank-one assumption for the quark-flavor matrix in semileptonic operators addressing B-meson anomalies, providing new constraints and experimental prospects.

## Key findings

- Large parameter space will be tested by upcoming flavor experiments
- Correlations between anomalies and high-$p_T$ observables are established
- Model constrains flavor violation directions in quark-flavor space

## Abstract

We assume that the quark-flavor coefficients matrix of the semileptonic operators addressing the neutral-current B-meson anomalies has rank-one, i.e. it can be described by a single vector in quark-flavor space. By correlating the observed anomalies to other flavor and high-$p_T$ observables, we constrain its possible directions and we show that a large region of the parameter space of this framework will be explored by flavor data from the NA62, KOTO, LHCb and Belle II experiments.
