A complete study of the one-loop induced decay Z -> neutrino antineutrino photon is presented within the framework of the Standard Model. The advantages of using a nonlinear gauge are stressed. We have found that the main contributions come from the electric dipole and the magnetic dipole transitions of the Z gauge boson and the neutrino, respectively. We obtain a branching ratio B=7.16E-10, which is about four orders of magnitude smaller than the bound recentely obtained by the L3…

Implications of Yukawa textures in the decay H+ → W+γ within the 2HDM-III

We discuss the implications of assuming a four-zero Yukawa texture for the charged Higgs decay H+ → W+γ at the one-loop level, within the context of the general two-Higgs doublet model of type III.
Bounds on the dipole moments of the tau-neutrino via the process $e^{+}e^{-}\rightarrow \nu \bar{\nu}\gamma$ in a 331 model
We obtain limits on the anomalous magnetic and electric dipole moments of the ντ through the reaction $e^{+}e^{-}\allowbreak\rightarrow \nu \bar{\nu}\gamma$ and in the framework of a 331 model. We

We study the one-loop sensitivity of the WWV (V={gamma},Z) vertex to the new massive gauge bosons predicted by the minimal SU{sub L}(3)xU{sub X}(1) model, which have unusual couplings to the standard
Fingerprinting the contribution of colored scalars to the $$H^+ W^- Z(\gamma )$$ vertex

Color-octet scalars arise in various Grand Unification scenarios and also in other models of new physics. They are also postulated for minimal flavour violation. Purely phenomenological imprints of
