Flipped Heavy Neutrinos from the Solar Neutrino Problem to Baryogenesis
J. Ellis, D. V. Nanopoulos, K. Olive
We discuss baryogenesis using the flipped model for lepton mass matrices. We show that the generalized see-saw mechanism in this model can not only provide MSW neutrino mix…
Supersymmetry Tests at Fermilab: A Proposal
J. Lopez, D. Nanopoulos, X. Wang +1
We compute the number of trilepton events to be expected at Fermilab as a result of the reaction , where is the lightest chargino and is…
Proposed Tests for Minimal SU(5) Supergravity at Fermilab, Gran Sasso, SuperKamiokande, and LEP
J. Lopez, D. Nanopoulos, H. Pois +1
A series of predictions are worked out in order to put the minimal supergravity model under experimental test. Using the two-loop gauge coupling renormalization group equat…
The Simplest, String-Derivable, Supergravity Model and its Experimental Predictions
J. Lopez, D. Nanopoulos, A. Zichichi
We present the simplest, string-derivable, supergravity model and discuss its experimental consequences. This model is a new string-inspired flipped which unifies at the st…
Proton Decay and Cosmology Strongly Constrain the Minimal SU(5) Supergravity Model
J. Lopez, D. Nanopoulos, H. Pois
We present the results of an extensive exploration of the five-dimensional parameter space of the minimal supergravity model, including the constraints of a long enough pro…
Testing Quantum Mechanics in the Neutral Kaon System
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
The neutral kaon system is a sensitive probe of quantum mechanics. We revive a parametrization of non-quantum-mechanical effects that is motivated by considerations of the nature o…
New Constraints on Neutralino Dark Matter in the Supersymmetric Standard Model
S. Kelley, J. Lopez, D. Nanopoulos +2
We investigate the prospects for neutralino dark matter within the Supersymmetric Standard Model (SSM) including the constraints from universal soft supersymmetry breaking and radi…
The prospects for CHORUS and NOMAD in the light of COBE and GALLEX
J. Ellis, J. Lopez, D. Nanopoulos
The most natural MSW neutrino oscillation interpretation of the GALLEX and other solar neutrino data, which invokes $m_{ν_μ}\sim3\times10^{-3}\eV$, and a general GUT see-saw hierar…
Troubles with the Minimal SU(5) Supergravity Model
J. Lopez, D. Nanopoulos, A. Zichichi
We show that within the framework of the minimal supergravity model, radiatively-induced electroweak symmetry breaking and presently available experimental lower bounds on…
Aspects of Radiative Electroweak Symmetry Breaking in Supergravity Models
S. Kelley, J. Lopez, D. Nanopoulos +2
We discuss several aspects of state-of-the-art calculations of radiative electroweak symmetry breaking in supergravity models. These models have a five-dimensional parameter space…
Constraints From Gauge Coupling Unification On The Scale Of Supersymmetry Breaking
John Ellis, S. Kelley, D. V. Nanopoulos
We reanalyze precision LEP data and coupling constant unification in the minimal supersymmetric model including the evolution of the gaugino masses. We derive general bound…
