TL;DR

This paper discusses a U(1) gauge extension of the supersymmetric standard model that predicts leptoquarks, links to dark matter, and features a unique neutrino mass matrix structure, offering new insights into particle interactions.

Contribution

It introduces a specific anomaly-free U(1) gauge extension with novel phenomenological predictions, including leptoquarks and dark matter components.

Findings

Leptoquarks are predicted with specific couplings to heavy neutrinos.

The model's neutrino mass matrix may have two zero subdeterminants.

The model is anomaly-free and conserves baryon and lepton numbers.

Abstract

A remarkable U(1) gauge extension of the supersymmetric standard model was proposed eight years ago. It is anomaly-free, has no mu term, and conserves baryon and lepton numbers automatically. The phenomenology of a specific version of this model is discussed. In particular, leptoquarks are predicted, with couplings to the heavy singlet neutrinos, the scalar partners of which may be components of dark matter. The Majorana neutrino mass matrix itself may have two zero subdeterminants.
