The `μ from ν' supersymmetric standard model (μνSSM) solves the μ problem of supersymmetric models and reproduces neutrino data, simply using couplings with the three families of right-handed neutrinos ν's. Novel signatures of supersymmetry at the LHC are expected through these new states, and couplings breaking R parity. All supersymmetric particles are potential candidates for the lightest one, which is not stable leading to prompt or displaced vertices and producing final states with multi-leptons/taus/jets/photons and missing energy. Besides, a decaying gravitino turns out to be an interesting candidate for dark matter. It can be searched through gamma-ray observations, such as those of the Fermi Large Area Telescope. The latter, depending on the region of the parameter space of the model, already imposes an upper bound on the gravitino mass of the order of 5-20 GeV and a lower bound on the lifetime of about 1025-28 s.
