B-decay anomalies in Pati-Salam SU(4)

TL;DR

This paper explores the Pati-Salam SU(4) model as a framework to explain B-decay anomalies while addressing the lack of signals in related experiments, integrating a new strongly interacting sector for Higgs boson production.

Contribution

It extends previous models by incorporating a Pati-Salam SU(4) symmetry with a strongly interacting sector to coherently explain B-decay anomalies.

Findings

Provides a detailed model connecting B-decay anomalies with Pati-Salam symmetry.

Addresses experimental constraints from related low and high energy experiments.

Proposes a unified framework for flavor anomalies and Higgs boson origin.

Abstract

Attempts to incorporate in a coherent picture the $B$-decay anomalies presumably observed in $b\rightarrow c$ and $b\rightarrow s$ semi-leptonic decays have to face the absence of signals in other related experiments, both at low and at high energies. By extending and making more precise the content of Ref. [1], we describe one such attempt based on the Pati-Salam SU(4) group, that unifies colour and the $B$-$L$ charge, in the context of a new strongly interacting sector, equally responsible for producing a pseudo-Goldstone Higgs boson.
