Lepton flavor violation and electric dipole moments from an intermediate scale in SUSY grand unification
N. G. Deshpande, B. Dutta, E. Keith
We show how an intermediate gauge symmetry breaking scale can be a source of lepton flavor violation and EDM of electron and neutron in SUSY GUTs. The Universal soft supersymmetry…
Single Isospin Decay Amplitude and CP Violation
N. G. Deshpande, Xiao-Gang He, Sandip Pakvasa
We study partial rate asymmetry in decays with single isospin final state. For K meson or hyperon decays, the partial rate asymmetries are always zero if the final states are singl…
On Measuring CP Violating Phase Using Neutral Decays
N. G. Deshpande, Sechul Oh
We propose two independent methods to determine the CKM phase and the tree and penguin amplitudes using neutral decays, assuming that the phase is known. Based on flavo…
Penguin Decays and
N. G. Deshpande, Xiao-Gang He
The penguin mediated processes and are studied. In the Standard Model, for the leptonic modes improvement in experimental limits will put…
Proton Decay In Supersymmetric Finite Grand Unificatione
N. G. Deshpande, Xiao-Gang He, E. Keith
We study proton decay in finite supersymmetric SU(5) grand unified theories. We find that the finite supersymmetric SU(5) models are ruled out from this consideration.
A Separate Higgs?
V. Barger, N. G. Deshpande, J. L. Hewett +1
We investigate the possibility of a multi-Higgs doublet model where the lightest neutral Higgs boson () decouples from the fermion sector. We are partially motivated by the fo…
