Radiative W and Z Decays and Spontaneous R-Parity Violation
نویسنده
چکیده
We point out that in a class of supersymmetric models where R-parity violation is induced by the spontaneous breaking of local B − L symmetry, the R-parity violating W decay W → l̃γ and Z decay Z → ν̃γ, forbidden in the minimal supersymmetric standard model (MSSM), occur at an enhanced rate compared to other models with R-parity breaking. We find that the branching fractions for these modes can be of order 10−5 .

Constraints on R–parity violating couplings from lepton universality
We analyze the one loop corrections to leptonic W and Z decays in an R– parity violating extension to the Minimal Supersymmetric Standard Model (MSSM). We find that lepton universality violation in the Z line–shape variables alone would strengthen the bounds on the magnitudes of the λ couplings, but a global fit on all data leaves the bounds virtually unchanged at |λ33k| ≤ 0.42 and |λ23k| ≤ 0.5...
متن کاملSpontaneous R - Parity violation bounds
We investigate bounds from tree-level and one-loop processes in generic supersymmetric models with spontaneous R-parity breaking in the superpotential. We analyse the bounds from a general point of view. The bounds are applicable both for all models with spontaneous R-parity violation and for explicit bilinear R-parity violation based on general lepton-chargino and neutrino-neutralino mixings. ...
متن کاملSingle Photon Decays of the Z and Susy with Spontaneously Broken R-parity
Spontaneous violation of R parity can induce rare single photon decays of the Z involving the emission of (nearly) massless pseudoscalar Goldstone bosons, majorons, as well as massive CP even or CP odd spin zero bosons that arise in the electroweak breaking sector of these models. We show that the majoron emitting decays can have a sizeable branching ratio of 10 or so, without conflicting any e...
متن کاملSpontaneous R-parity violation and the origin of neutrino mass
We study the phenomenology of supersymmetric models that explain neutrino masses through the spontaneous breaking of R-parity, finding strong correlations between the decays of the lightest neutralino and the neutrino mixing angles. In addition, the existence of a Goldstone boson, usually called Majoron (J), completely modifies the phenomenology with respect to the standard picture, inducing la...
متن کاملLepton flavour violation in Little Higgs model with T-Parity
If neutrino mass and mixing consistent with the neutrino oscillation data are the only source of lepton flavor violation (LFV)in nature, the other LFV decays like the radiative and semileptonic decays would be too small to be observed experimentally in the foreseeable future. These decays have been the objects of recent Belle measurments. We analyze LFV in Little Higgs Model with T-parity and f...
