LSP Squark Decays at the LHC and the Neutrino Mass Hierarchy

Understand

The existence of R-parity in supersymmetric models can be naturally explained as being a discrete subgroup of gauged baryon minus lepton number (B-L).

• The most minimal supersymmetric B-L model triggers spontaneous R-parity violation, while remaining consistent with proton stability.
• This model is well-motivated by string theory and makes several interesting, testable predictions.
• Furthermore, R-parity violation contributes to neutrino masses, thereby connecting the neutrino sector to the decay of the lightest supersymmetric particle (LSP).
