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…
Probing Neutrino Parameters at Accelerators
J. C. Romao
The simplest unified extension of the Minimal Supersymmetric Standard Model with bilinear R--Parity violation provides a predictive scheme for neutrino masses which can account for…
Spontaneous CP Violation in Non-Minimal Supersymmetric Models
Cyril Hugonie, Jorge C. Romao, Ana M. Teixeira
We study the possibilities of spontaneous CP violation in the Next-to-Minimal Supersymmetric Standard Model with an extra singlet tadpole term in the scalar potential. We calculate…
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…
