The flavour-changing radiative decay of the t quark has been considered at one loop level in a nonlinear Rξ gauge within the standard model and beyond. The electroweak penguin diagrams involving one insertion of the W boson and/or scalar particle ha

The decay of the fourth-generation down-type quark b' → bγ and b' → bg has been studied as an extension of the standard model using evolution of the mass-based fourth generation CKM matrix with CP violation phase equal to zero. Range of the mass

We examine the indirect effect of the new physics. The virtual effects of the trilinear gauge coupling of the photon to W+W- on the b → sγ decay has been tested considering the possibility of the fourth generation in the quark sector, with correct

The effective bsZ vertex may be influenced by tree uu˘Z vertex formed by a mixing with heavy exotic isosinglet up-type quarks. The electroweak penguin diagrams involving one insertion of the uu˘Z vertex have been considered and we have calculated t
