Towards a unified explanation of $R_{D^{(\ast)}}$, $R_{K}$ and $(g-2)_{\mu}$ anomalies in a left-right model with leptoquarks

TL;DR

This paper proposes a minimal left-right symmetric model with leptoquarks that simultaneously explains B-decay anomalies and the muon g-2 discrepancy, aligning with current experimental constraints.

Contribution

It introduces a unified theoretical framework based on a left-right symmetric gauge theory to address multiple flavor and magnetic moment anomalies.

Findings

Consistent explanation of R_D(*) and R_K anomalies.

Accounts for muon g-2 discrepancy.

Aligns with existing decay and mixing constraints.

Abstract

We present a unified explanation for the $B$-decay anomalies in $R_{D^{(\ast)}}$ and $R_{K}$ together with the anomalous muon magnetic moment, consistent with the constraints from the current measurements of leptonic decay rates and $D^0-\bar{D}^0$, $B_{s}^0-\bar{B}_{s}^0$ mixings, within the framework of a minimal left-right symmetric gauge theory motivated by one of the low-energy subgroups of $E_{6}$ naturally accommodating leptoquarks.
