The μ-from-ν supersymmetric standard model (μνSSM) offers a solution to the μ-problem and simultaneously accommodate massive neutrinos through R-parity violation and a TeV scale seesaw using a set of right-handed neutrino superfields. In this model a very light neutralino can still decay inside the LHC detector through an available even lighter scalar/pseudoscalar state, with light neutralino to lighter scalar/pseudoscalar + neutrino decay mode. We emphasize how this unique feature can be utilized to study a non-standard Higgs signal at the LHC, with Higgs to a pair of light neutralino decay mode. We demonstrate how μνSSM can manifest itself through events with displaced multileptons at the LHC and provides unique signature for the model.
