New Astrophysical Constraints on the Mass of the Superlight Gravitino
J. A. Grifols, R. N. Mohapatra, A. Riotto
In some supergravity models, the superlight gravitino is accompanied by a light weakly coupled scalar (S) and pseudo-scalar (P) particle. The coupling of these particles to matter…
Supersymmetric models with anomalous U(1) mediated supersymmetry breaking
R. N. Mohapatra, A. Riotto
We construct realistic supergravity models where supersymmetry breaking arises from the D-terms of an anomalous U(1) gauge symmetry broken at the Planck scale. Effective action for…
Astrophysical bounds on superlight gravitinos
J. A. Grifols, R. N. Mohapatra, A. Riotto
We derive the allowed mass range for the superlight gravitino present in a large class of supersymmetric models from the observed luminosity from Supernova 1987A. We find that for…
Anomalous Mediated SUSY Breaking, Fermion Masses and Natural Suppression of FCNC and CP Violating Effects
R. N. Mohapatra, Antonio Riotto
We construct realistic supergravity models where supersymmetry breaking arises from the -terms of an anomalous gauge symmetry broken at the Planck scale. The model has th…
Higgs Boson Mass in Models with Gauge-Mediated Supersymmetry Breaking
A. Riotto, O. Tornkvist, R. N. Mohapatra
We present the predictions for the mass of the lightest Higgs boson in models with gauge-mediated supersymmetry breaking as a function of the SUSY-breaking scale. We include…
New Supernova Constraints on Sterile Neutrino Production
E. W. Kolb, R. N. Mohapatra, V. L. Teplitz
We consider the possibility that a light sterile-neutrino species can be produced by scattering during the cooling of a proto-neutron star. If we parameterize the steri…
Neutron-anti-neutron oscillation as a test of grand unification
R. N. Mohapatra
We discuss the predictions for neutron-anti-neutron oscillation in various supersymmetric and non-supersymmetric grand unified theories. It is pointed out that in a new class of su…
Structures in the Mirror Universe
R. N. Mohapatra, Vigdor L. Teplitz
The idea of the universe with a mirror sector having all particles and forces identical to those in the familiar sector has been proposed in the context of neutrino physics as well…
Unification, Seesaw Mechanism and R-Conservation
R. N. Mohapatra
A new supersymmetric grand unified model based on the gauge group is discussed. The model has the feature that the conventional seesaw mechanism for neutrino ma…
