The Minimal Theory for R-parity Violation and the LHC

Studies in the MSSM usually assume the existence of an ad hoc discrete symmetry, R-parity, which stabilizes the proton and eliminates many unknown SUSY parameters. It furthermore has consequences for the most well known SUSY predictions: missing energy and stable dark matter. I will discuss the simplest framework for determining the fate of R-parity (B-L symmetries) and show that even in cases where R-parity is violated, realistic models exist. Such models hold further consequences for the neutrino sector and collider phenomenology.
