Description
An appealing framework for suppressing proton decay in supersymmetry is by considering models with gauged B-L symmetries. This is because R-parity is a subgroup of B-L. The minimal supersymmetric B-L model must violate B-L in such a way to spontaneous break R-parity, but keeps the proton safe. In this context, R-parity violation both generates neutrino masses and allows for the decay of the LSP. This suggests that one can potentially learn about the neutrino sector from collider observations of LSP decays. I will briefly introduce this minimal model and discuss how stop LSP decays can reveal information about the neutrino hierarchy and therefore determine neutrino masses.
