The Decay Rate Asymmetry of the Top Quark
The asymmetries Ak ≡ [Γ(t → Wdk)−Γ(t̄ → Wd̄k)]/[Γ(t → Wdk)+Γ(t̄ → Wd̄k)] in the partial widths of the top quark decays are discussed within the Standard Model (SM), the Two-Higgs-Doublet Model (2HDM) and supersymmetric extensions of the SM (SSM). The leading contributions to these asymmetries in the SM and in the 2HDM are induced by the up-type quark self-energy diagrams and are found to be very sm...
متن کاملDecay Rate Asymmetry of the Top Quark through Light
A decay rate asymmetry of the top quark is discussed within the framework of the supersymmetric standard model. Although new sources of CP violation in this model are severely constrained from the electric dipole moments of the neutron and the electron, there is a possibility that a top squark has a mass of around 100 GeV and CP violation in its interaction with a top quark is unsuppressed. The...
متن کاملSpectral asymmetry and supersymmetry
Fractional charges, and in particular the spectral asymmetry η of certain Dirac operators , can appear in the central charge of supersymmetric field theories. This yields unexpected analyticity constraints on η from which classic results can be recovered in an elegant way. The method could also be applied in the context of string theory.
متن کاملDecay rate asymmetry for B → Xsγ in SUSY model
We discuss a rate asymmetry for the radiative B-meson decay B → Xsγ within the framework of the supersymmetric standard model based on N = 1 supergravity. This model contains new sources of CP violation. In spite of severe experimental constraints on the electric dipole moment of the neutron, a new CP-violating phase may not be suppressed, leading to a sizable enhancement of the decay rate asym...
متن کاملSmallness of Baryon Asymmetry from Split Supersymmetry
The smallness of the baryon asymmetry in our universe is one of the greatest mysteries and may originate from some profound physics beyond the standard model. We investigate the Affleck-Dine baryogenesis in split supersymmetry, and find that the smallness of the baryon asymmetry is directly related to the hierarchy between the supersymmetry breaking squark/slepton masses and the weak scale. Put...
