Simple models with both baryon and lepton number violation by two units


Abstract in English

We construct simple renormalizable extensions of the standard model where the leading baryon number violating processes have $Delta B = pm Delta L = -2$. These models contain additional scalars. The simplest models contain a color singlet and a colored sextet. For such baryon number violation to be observed in experiments, the scalars cannot be much heavier than a few TeV. We find that such models are strongly constrained by LHC physics, LEP physics, and flavor physics.
