Scalar Leptoquarks, Baryon Number Violation and Pati-Salam Symmetry

TL;DR

This paper explores how scalar leptoquarks at TeV scales, embedded in a Pati-Salam model, can address flavor anomalies while suppressing baryon number violation, extending previous work on vector leptoquarks.

Contribution

It analyzes the impact of scalar leptoquarks within Pati-Salam models on baryon number violation, providing a theoretical framework that extends prior vector leptoquark studies.

Findings

Scalar leptoquarks can explain flavor anomalies.

Embedding in Pati-Salam models suppresses baryon number violation.

Extension of previous vector leptoquark results.

Abstract

One or more scalar leptoquarks with masses around a few TeV may provide a solution to some of the flavor anomalies that have been observed. We discuss the impact of such new degrees on baryon number violation when the theory is embedded in a Pati-Salam model. The Pati-Salam embedding can suppress renormalizable and dimension-five baryon number violation in some cases. Our work extends the results of Assad, Grinstein, and Fornal who considered the same issue for vector leptoquarks.
