Leptoquarks with exactly stable protons


Davighi, Joe; Greljo, Admir; Thomsen, Anders Eller (2022). Leptoquarks with exactly stable protons. Physics Letters B, 833:137310.

Abstract

We explore a novel mechanism to restrict TeV-scale leptoquark interactions and render the proton exactly stable to all orders in the effective field theory expansion. A scalar condensate breaks a lepton-flavoured gauge symmetry in the ultraviolet and generates neutrino masses, leaving a discrete or gauge symmetry in the infrared, forbidding processes. This provides an elegant framework to address the flavour anomalies and can be adapted to many other new-physics models. The can emerge from a gauge–flavour unified theory at even higher energies.
