Can flavor-independent supersymmetric soft phases Be the source of all CP violation?
Recently it has been demonstrated that large phases in softly broken supersymmetric (SUSY) theories are consistent with electric dipole moment constraints, and are motivated in some (type I) string models. Here we consider whether large flavor-independent soft phases may be the dominant (or only) source of all CP violation. In this framework, epsilon and epsilon(')/epsilon can be accommodated, ...

Recently it has been demonstrated that large phases in softly broken supersymmetric theories are allowed by electric dipole moment constraints, and are motivated in some string models. Here we consider whether large soft phases in the supersymmetry breaking sector may be the dominant (or only) source of all CP violation, and demonstrate that ǫ and ǫ/ǫ can be described. We show that in the prese...
متن کاملCan the Supersymmetric Flavor Problem Decouple? *
It has been argued that the squarks and sleptons of the first and second generations can be relatively heavy without destabilizing the weak scale, thereby improving the situation with too-large flavorchanging neutral current (FCNC) and CP violating processes. In theories where the soft supersymmetry breaking parameters are generated at a high scale (such as the Planck scale), we show that such ...
متن کاملDelayed phases of contrast MRI, can it be valuable in multiple sclerosis active phase diagnosis?
Background: Observing the enhancing plaques in magnetic resonance imaging (MRI) is one of the most valuable diagnostic modalities in confirming the diagnosis of multiple sclerosis (MS), its recurrence and for better detection of active disease. Since active lesions discovery can improve designating diffusion in time diagnosis of MS and controlling disease activity, and there is not any definite...
متن کاملThe Supersymmetric Flavor Problem
The supersymmetric SU(3)×SU(2)×U(1) theory with minimal particle content and general soft supersymmetry breaking terms has 110 physical parameters in its flavor sector: 30 masses, 39 real mixing angles and 41 phases. The absence of an experimental indication for the plethora of new parameters places severe constraints on theories posessing Planck or GUT-mass particles and suggests that theories...
