Neutron And Electron Electric Dipole Moment In N=1 Supergravity Unification, Tarek Ibrahim, Pran Nath
Neutron And Electron Electric Dipole Moment In N=1 Supergravity Unification, Tarek Ibrahim, Pran Nath
Pran Nath
An analysis of the neutron EDM and of the electron EDM in minimal N=1 supergravity unification with two CP-violating phases is given. For the neutron the analysis includes the complete one loop gluino, chargino, and neutralino exchange diagrams for the electric dipole and the chromoelectric dipole operators, and also the contribution of the purely gluonic dimension-six operator. It is shown that there exist significant regions in the six-dimensional parameter space of the model where cancellations between the gluino and the chargino exchanges reduce the electric and the chromoelectric contributions, and further cancellations among the electric, the chromoelectric, and the purely …

Neutron And Lepton Electric Dipole Moments In The Minimal Supersymmetric Standard Model, Large Cp Violating Phases, And The Cancellation Mechanism, Tarek Ibrahim, Pran Nath
Pran Nath
An analysis of the electric dipole moment (EDM) of the neutron and of the lepton in the minimal supersymmetric standard model (MSSM) with the most general allowed set of CP violating phases without generational mixing is given. The analysis includes the contributions from the gluino, the chargino and the neutralino exchanges to the electric dipole operator, the chromoelectric dipole operator, and the CP violating purely gluonic dimension six operator. It is found that the EDMs depend only on certain combinations of the CP phases. The independent set of such phases is classified. The analysis of the EDMs given here provides …
