Baryonic violation of R parity from anomalous U ( 1 ) H
/ Authors
/ Abstract
Supersymmetric scenarios with $R$-parity conservation are becoming very constrained due to the lack of missing energy signals associated to heavy neutral particles, thus motivating 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. A self-consistent framework with baryon-number violation is achieved along with a proper suppression for lepton-number violating dimension-five operators, so that the proton can be sufficiently stable. 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.
