The mu-from-nu supersymmetric standard model arises from the use of right-handed neutrino superfields in order to avoid a possible mu-problem and reproduce neutrino physics experiments. This model breaks R-parity explicitly and involves a single scale ? that of the soft-breaking-terms. This scale is expected to be very close to the electroweak scale. In addition, the breaking of R-parity and the origin of the mu-term are intimately related with neutrino physics. These features give a rich phenomenology, opening the possibility of clear signals of new physics at the LHC. In this talk we describe how displaced vertices can be detected at the LHC trough the Higgs production. The Higgs is decaying to two light neutralino, with the following decay of the long life neutralino to displaced taus.
