Baryonic violation of R-parity from anomalous $U(1)_H$

TL;DR

This paper proposes a supersymmetric model with an anomalous horizontal $U(1)_H$ symmetry that allows baryon-number violation while suppressing lepton-number violation, accommodating neutrino masses, and addressing collider phenomenology.

Contribution

It introduces a novel supersymmetric framework with baryonic R-parity violation and an anomalous $U(1)_H$ symmetry, ensuring proton stability and neutrino mass generation.

Findings

Baryon-number violation is achieved with suppressed lepton-number violation.

The model accommodates both Dirac and Majorana neutrino masses.

Implications for collider experiments are discussed.

Abstract

Supersymmetric scenarios with R-parity conservation are becoming very constrained due to the lack of missing energy signals, thus motivating those scenarios with R-parity violation. In view of this, we consider a supersymmetric model with R-parity violation and extended by an anomalous horizontal $U(1)_H$ symmetry, where a self-consistent framework with baryon-number violation is achieved along with a proper supression for lepton number violating dimension-5 operators in order to keep a proton decay safe. With the introduction of right-handed neutrinos both Dirac and Majorana masses can be accommodated within this model. The implications for collider physics are discussed.
