As a result, the prediction for as in simple grand unified theories is 3s 5s closer to the experimental value, and the allowed CP-violating phases are larger by one to two orders of magnitude. In addition, the very heavy top and bottom

CP violation beyond the standard model*

3 An important point isthat complex phases may not lead to physically observable CP violation. This isa well-known aspect of spontaneous CP violation in field theory, but it applies equally to string theories as discussed by Dent [3]. In heterotic string models, CP is preserved by any (generally complex) moduli vev s that lie on the boundary

CP violation in supersymmetric theories

CP violation will be obtained from the B-factory soon, which would be a crucial test of the CP violation in SM. Furthermore, SM model is unable to explain the cosmological baryon asymmetry of our universe, the presence of new sources of CP violation is required for this explanation.

CP violation. There should be a mechanism which controls FCNC and CP. This may be due to the SUSY breaking/mediation mechanism and/or flavor symmetry. We can get a clue to these mechanisms by studying FCNC and CP violation in supersymmetric models. Mass insertion approximation is a useful tool to present flavor violation through sfermions. (δd

At the phenomenological, 2 Higgs Doublets Models (2HDMs) could provide scalar mediated contributions to avour changing neutral K0{K 0 mixing and thus explain the observed CP Violation in the context of two quark generations.

The CP violation in the Kand Bdmeson decays has been successfully explained within the framework of the standard model (SM), so called Kobayashi-Maskawa (KM) model [2]. However, there are a possibility of new sources of the CP violation if the SM is extended to the supersymmetric (SUSY) models.

We consider the contributions to e, e'/e and the electric dipole moments due to flavor blind mechanisms of CP violation, found in supersymmetric models. Many mechanisms have been proposed to account for one piece of experimental data, namely CP violation in the K0-K 0 system.

Another interesting motivation for SCPV arises from the strong CP problem. As far as CP is a good symmetry the QCD phase θ is zero. The spontaneous breaking of CP could respect this initial value of θ while creating the observed weak CP violation [6, 7]. Such scenarios find a natural framework in left-right models, where it was recently

of T-violation (or CP-violation, on assuming the CPT theorem) in the strong inter-actions had some theoretical underpinning. Indeed, QCD allows for the addition of a dimension-four term, known as the h-term, with a dimensionless coefficient h which, if non-zero, would signify the violation of both P and T. This term is some-

The purpose of this review is to bridge this gap. Thus in this review we present a broad overview of CP violation starting from the Standard Model and ending with strings.

Nucleon Electric Dipole Moments in High Scale Supersymmetric

Such models, predict very heavy sfermions, are called high-scale supersymmetric models. Actu-ally, 102 3 TeV sfermion mass can explain 125 GeV Higgs boson [2 4] and such value of mass is sufficient to suppress CP violation and FCNC [5] So we consider the model as sfermion mass to be 102 3 TeV. There are also some problems related to cosmology.

For ex-ample, the matter antimatter asymmetry in the early universe can be generated at the electroweak phase transition if the transition is sufficiently first-order [25].

Moreover, we always take a vanishing phase in the CKM matrix, i.e. SCKM = 0, as a way to isolate the effects of the new supersymmetric phases.

Higher-Order Contributions in Higgs Sectors of Supersymmetric

Supersymmetric models like the Minimal Supersymmetric Model (MSSM) or the Next-to MSSM fall into this category. In the MSSM, the mass of the lightest Higgs boson can be predicted from other parameters in the theory. In this case, the mass measurement of the newly discovered boson can be exploited to constrain the parameters of the underlying

We study the possibility of spontaneous CP violation in the next-to-minimal supersymmetric standard model (NMSSM). It is shown that the spontaneous CP violation is induced by the radiative effects of top, stop, bottom and sbottom superfields.
