We investigate the simplest gauge theory for spontaneous R-parity breaking
and its testability at the LHC. This theory based on a local B-L gauge symmetry
can be considered as the simplest framework for understanding the origin of the
R-parity violating interactions, giving rise to potential lepton number
violating signals and suppressed baryon number violating operators. The full
spectrum of the theory and the constraints coming from neutrino masses are
analyzed in great detail. We discuss the proton decay issue and the possible
dark matter candidates. In order to assess the testability of the theory we
study the properties of the new gauge boson, the neutralino decays and the main
production channels for the charged sleptons at the LHC. We find that the
channels with four charged leptons, three of them with the same sign, and four
jets give us the most striking signals for the testability of lepton number
violation at the LHC.
