Cp Violating Lepton Asymmetries in Left-right Models
Lepton charge asymmetries can be used as an alternative means of searching for new physics. They are interesting because they are small in the Standard Model and therefore, necessarily evidence new physics. In this work we explore the use of lepton asymmetries as a probe of the flavour structure of the left-right symmetric model with spontaneous CP violation. We find that new physics may enhanc...
متن کاملMajorana CP-Violating Phases, RG Running of Neutrino Mixing Parameters and Charged Lepton Flavour Violating Decays
We consider the MSSM with see-saw mechanism of neutrino mass generation and soft SUSY breaking with flavour-universal boundary conditions at the GUT scale, in which the lepton flavour violating (LFV) decays μ → e + γ, τ → μ + γ, etc., are predicted with rates that can be within the reach of present and planned experiments. These predictions depend critically on the matrix of neutrino Yukawa cou...
متن کامل1 CP violating transverse lepton polarizaion in B → D ( ∗ ) l ν̄ including tensor interactions
We give a model-independent analysis of CP violating lepton polarization in the exclusive semileptonic B decay of B → D(∗)lν̄ including dimension six four-fermion tensor interactions at the heavy quark limit. It is shown that the tensor interactions should not be neglected if the associated couplings are comparable to others. The effect of tensor interactions on the transverse polarization appea...
متن کاملLepton Dipole Moments and Rare Decays in the CP-violating MSSM with Nonuniversal Soft-Supersymmetry Breaking
We investigate the muon anomalous magnetic dipole moment (MDM), the muon electric dipole moment (EDM) and the lepton-flavour-violating decays of the τ−lepton, τ → μγ and τ → 3μ, in the CP-violating Minimal Supersymmetric Standard Model (MSSM) with nonuniversal softsupersymmetry breaking. We evaluate numerically the muon EDM and the branching ratios B(τ → μγ) and B(τ → 3μ), after taking into acc...
متن کاملCP–Violating Invariants in Supersymmetry
I study the weak basis CP-violating invariants in supersymmetric models, in particular those which cannot be expressed in terms of the Jarlskog–type invariants, and find basis–independent conditions for CP conservation. With an example of the K − K̄ mixing, I clarify what are the combinations of supersymmetric parameters which are constrained by experiment.
