Description

It is commonly stated that in R-parity violating supersymmetric models, the simultaneous presence of renormalizable B and L-violating interactions is heavily constrained as they induce 2-body proton decay. In this talk, I will point out that certain LLE couplings which are anti-symmetric in flavor indices will instead induce 4-body proton decay when combined with UDD couplings. The resulting 4-body phase space suppression significantly weakens proton decay bounds, allowing both the LLE and UDD couplings to be simultaneously non-negligible and relevant for collider phenomenology. I present a simple model which can potentially account for such a flavor structure in the L-violating couplings. I also discuss implications for LHC phenomenology, and highlight qualitative differences from the usual R-parity violating scenarios.
