Neutrino Unification
P. H. Chankowski, A. Ioannisian, S. Pokorski +1
Present neutrino data are consistent with neutrino masses arising from a common seed at some ``neutrino unification'' scale . Such a simple theoretical ansatz naturally leads…
Broken R Parity, Neutrino Anomalies and Collider Tests
M. Hirsch, W. Porod, J. Romao +1
The solar and atmospheric neutrino anomalies constitute the only solid and most remarkable evidence for physics beyond the Standard Model, indicating that the lepton mixing matrix…
Bilinear R-parity violating SUSY: Solving the solar and atmospheric neutrino problems
M. Hirsch, W. Porod, J. W. F. Valle +2
Bilinear R-parity violation is a simple extension of the MSSM allowing for Majorana neutrino masses. One of the three neutrinos picks up mass by mixing with the neutralinos of the…
Bilinear R-parity Violation and Small Neutrino Masses: a Self-consistent Framework
J. M. Mira, E. Nardi, D. A. Restrepo +1
We study extensions of supersymmetric models without R-parity which include an anomalous U(1)_H horizontal symmetry. Bilinear R-parity violating terms induce a neutrino mass at tre…
Neutralino Phenomenology at LEP2 in Supersymmetry with Bilinear Breaking of R-parity
A. Bartl, W. Porod, D. Restrepo +2
We discuss the phenomenology of the lightest neutralino in models where an effective bilinear term in the superpotential parametrizes the explicit breaking of R-parity. We consider…
Light Stop: MSSM versus R-parity violation
W. Porod, D. Restrepo, J. W. F. Valle
We discuss the phenomenology of the lightest stops in models where R-parity is broken by bilinear terms. In this class of models we consider scenarios where the R-parity breaking t…
