Texture of fermion mass matrices in partially unified theories
B. Dutta, S. Nandi
We investigate the texture of fermion mass matrices in theories with partial unification (for example ) at a scale GeV. Startin…
A grand unified model with and GeV
N. G. Deshpande, B. Dutta, E. Keith
We present a model based on the gauge group SU(2)_L\times SU(2)_R \times SU(4)_C with gauge couplings that are found to be unified at a scale near the string unification scale. Thi…
Constraints from on gauge-mediated supersymmetry breaking models
N. G. Deshpande, B. Dutta, Sechul Oh
We consider the branching ratio of in gauge mediated supersymmetry breaking theories. Useful bounds on the parameter space of these models are derived from the experimen…
Jets and Partons
Davison E. Soper
Jet production in high energy hadron-hadron collisions can serve as a probe for new physics. I review recent data from CDF and D0 on the high E_T jet cross section. Reporting on re…
Probing the QCD pomeron in e+ e- collisions
Stanley J. Brodsky, Francesco Hautmann, Davison E. Soper
The total cross section for scattering virtual photons at high energy is sensitive to pomeron physics. If the photons are sufficiently virtual, QCD perturbation theory applies, so…
SUSY GUTs contributions and model independent extractions of CP phases
N. G. Deshpande, B. Dutta, Sechul Oh
We consider the origin of new phases in supersymmetric grand unification model, and show how significant new contributions arise from the gluino mediated diagram. We then present a…
