Probing the μνSSM with light scalars, pseudoscalars and neutralinos from the decay of a SM-like Higgs boson at the LHC
Abstract: The “μ from ν” supersymmetric standard model (μνSSM) can accommodate the newly discovered Higgs-like scalar boson with a mass around 125 GeV. This model provides a solution to the μ-problem and simultaneously reproduces correct neutrino physics by the simple use of right-handed neutrino su...

López-Fogliani, D.E. Mitsou, V.A. Muñoz, C. de Austri, R.R. Supersymmetry Phenomenology Abstract: The “μ from ν” supersymmetric standard model (μνSSM) can accommodate the newly discovered Higgs-like scalar boson with a mass around 125 GeV. This model provides a solution to the μ-problem and simultaneously reproduces correct neutrino physics by the simple use of right-handed neutrino superfields. These new superfields together with the introduced R-parity violation can produce novel and characteristic signatures of the μνSSM at the LHC. We explore the signatures produced through two-body Higgs decays into the new states, provided that these states lie below in the mass spectrum. For example, a pair produced light neutralinos depending on the associated decay length can give rise to displaced multi-leptons/taus/jets/photons with small/moderate missing transverse energy. In the same spirit, a Higgs-like scalar decaying to a pair of scalars/pseudoscalars can produce final states with prompt multi-leptons/taus/jets/photons. © 2014, The Author(s).
