The b -> sgg decay in the two and three Higgs doublet models with CP violating effects Goksu, A; Iltan, EO; Solmaz, L (2001-04-20) We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.
The radiative lepton flavor violating decays in the split fermion scenario in the two-higgs doublet model Iltan, E. O. (World Scientific Pub Co Pte Lt, 2007-04-10) We study the branching ratios of the lepton flavor violating processes mu --> e gamma, tau --> e gamma and tau --> mu gamma in the split fermion scenario, in the framework of the two-Higgs doublet model. We observe that the branching ratios are relatively more sensitive to the compactification scale and the Gaussian widths of the leptons in the extra dimensions, for two extra dimensions and especially for the tau --> mu gamma decay.
THE RARE DECAY B-]K-STAR-GAMMA IN THE STANDARD AND IN SUPERSYMMETRIC MODELS Alıyev, Tahmasıb; SLOBODENYUK, VA (1990-05-01)
The exclusive B-s ->phi l(+)l(-) decay in the two Higgs doublet models Erkol, G; Turan, Gürsevil (2002-11-01) We study the differential branching ratio, the branching ratio and the forward-backward asymmetry for exclusive B-s --> phil(+)l(-) decay in the two Higgs doublet model. We analyze the dependences of these quantities on the model parameters and show that these observables are highly sensitive to new physics and hence may provide a powerful probe of the SM and beyond.
The exclusive B ->pi l(+)l(-) and B ->rho l(+)l(-) decays in the general two Higgs doublet model Erkol, G; Turan, Gürsevil (2002-02-01) We study the differential branching ratio, branching ratio and the forward-backward asymmetry for the exclusive B --> pil(+)l(-) and B --> rhol(+)l(-) decays in the general two Higgs doublet model including the neutral Higgs boson erects. We analyze the dependencies of these quantities on the neutral Higgs boson contributions and the other model parameters. We observe that two Higgs doublet model with the neutral Higgs boson exchanges gives quite sizable contributions to these observables for both channels ...
