We investigate the possibility of obtaining sizeable R-parity-breaking interactions violating baryon number but not lepton number within supersymmetric grand unified theories. Such a possibility allows us to ameliorate the naturalness status of supersymmetry while maintaining successful gauge coupling unification, one of its main phenomenological motivations.

Abstract
We investigate the possibility of obtaining sizeable R-parity-breaking interactions violating baryon number but not lepton number within supersymmetric grand unified theories. Such a possibility allows us to ameliorate the naturalness status of supersymmetry while maintaining successful gauge coupling unification, one of its main phenomenological motivations. We show that this can be achieved without fine-tuning or the need of large representations in simple SO(10) models. © 2013 American Physical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
