Scalar leptoquarks, baryon number violation, and Pati-Salam symmetry

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.

This paper discusses the impact of scalar leptoquarks with masses around a few TeV on baryon number violation in a Pati-Salam model, showing that the Pati-Salam embedding can suppress baryon number violation in some cases. This work extends previous results on the same issue for vector leptoquarks by Assad, Grinstein, and Fornal.
