Phenomenological Tests of Supersymmetric A_4 Family Symmetry Model of Neutrino Mass
M. Hirsch, J. C. Romao, S. Skadhauge +2
Recently Babu, Ma and Valle proposed a model of quark and lepton mixing based on symmetry. Within this model the lepton and slepton mixings are intimately related. We perform…
Degenerate neutrinos from a supersymmetric A_4 model
M. Hirsch, J. C. Romao, S. Skadhauge +2
We investigate the supersymmetric A_4 model recently proposed by Babu, Ma and Valle. The model naturally gives quasi-degenerate neutrinos that are bi-largely mixed, in agreement wi…
Neutrino properties and the decay of the lightest supersymmetric particle
M. Hirsch, W. Porod
Supersymmetry with broken R-parity can explain the neutrino mass squared differences and mixing angles observed in neutrino oscillation experiments. In the minimal model, where R-p…
Testing the Mechanism of R-parity Breaking with Slepton LSP Decays
A. Bartl, M. Hirsch, T. Kernreiter +2
In supersymmetric models R-parity can be violated through either bilinear or trilinear terms in the superpotential, or both. If charged scalar leptons are the lightest supersymmetr…
Reconstructing Neutrino Properties from Collider Experiments in a Higgs Triplet Neutrino Mass Model
D. Aristizabal Sierra, M. Hirsch, J. W. F. Valle +1
We extend the minimal supersymmetric standard model with bilinear R-parity violation to include a pair of Higgs triplet superfields. The neutral components of the Higgs triplets de…
Solar Neutrino Masses and Mixing from Bilinear R-Parity Broken Supersymmetry: Analytical versus Numerical Results
M. A. Diaz, M. Hirsch, W. Porod +2
We give an analytical calculation of solar neutrino masses and mixing at one-loop order within bilinear R-parity breaking supersymmetry, and compare our results to the exact numeri…
CP Phases, LFV, RpV & all that
A. Bartl, K. Hidaka, M. Hirsch +6
Most phenomenological analyses of searches for supersymmetric particles have been performed within the MSSM with real SUSY parameters and conserved R-parity and lepton flavour. Her…
