Electron and Neutron Electric Dipole Moments in the Focus Point Scenario of SUGRA Model
Utpal Chattopadhyay, Tarek Ibrahim, D. P. Roy
We estimate the electron and neutron electric dipole moments in the focus point scenario of the minimal SUGRA model corresponding to large sfermion masses and moderate to large $\t…
LHC Signature of the Minimal SUGRA Model with a Large Soft Scalar Mass
Utpal Chattopadhyay, Amitava Datta, Anindya Datta +2
Thanks to the focus point phenomenon, it is quite {\it natural} for the minimal SUGRA model to have a large soft scalar mass m_0 > 1 TeV. A distinctive feature of this model is an…
Constraining Anomaly Mediated Supersymmetry Breaking Framework via Ongoing Muon g-2 Experiment at Brookhaven
Utpal Chattopadhyay, Dilip Kumar Ghosh, Sourov Roy
The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g-2 is promising to probe a theory involving supersymmetry. We have studied the constraints on the…
CP Violation and Dark Matter
Utpal Chattopadhyay, Tarek Ibrahim, Pran Nath
A brief review is given of the effects of CP violation on the direct detection of neutralinos in dark matter detectors. We first summarize the current developments using the cancel…
