A three-site gauge model for flavor hierarchies and flavor anomalies

TL;DR

This paper introduces a three-site Pati-Salam gauge model that explains flavor hierarchies and anomalies in B decays, predicting new TeV-scale states testable at the LHC.

Contribution

It proposes a novel three-site gauge model that simultaneously addresses flavor hierarchies and flavor anomalies in B decays, consistent with current bounds.

Findings

Predicts new states at TeV scale detectable at LHC

Explains flavor hierarchies within a Pati-Salam framework

Accounts for recent lepton-flavor non-universality hints

Abstract

We present a three-site Pati-Salam gauge model able to explain the Standard Model flavor hierarchies while, at the same time, accommodating the recent experimental hints of lepton-flavor non-universality in $B$ decays. The model is consistent with low- and high-energy bounds, and predicts a rich spectrum of new states at TeV scale that could be probed in the near future by the high-$p_T$ experiments at the LHC.
