We study the decay width T and CP asymmetry Acp of the inclusive process b - > sg in model III version of the two Higgs doublet model and the three Higgs doublet model with tree level flavor changing neutral currents, including QCD corrections. We analyzed the energy and sin0 dependencies of T and Acp, respecting the existing constrains coming from the experiments in the model III and 3HDM(02). We observe that there exists a considerable enhancement in the decay width and CP asymmetry of the b -> sg process. This enhancement can be measured in the near future experiments, which tests the validity of proposed models beyond the standard model.

B-s ->tau(+)tau(-)gamma decay in the general two Higgs doublet model including the neutral Higgs boson effects Erkol, G; Turan, Gürsevil (2002-05-01) We investigate the differential branching ratio, the branching ratio, differential forward-backward asymmetry, forward-backward asymmetry of the lepton pair, and lepton polarization asymmetry of the exclusive B-s-->tau(+)tau(-)gamma decay in the general two Higgs doublet model including the neutral Higgs boson effects. We analyze the dependences of these quantities on the model parameters and also on the neutral Higgs boson effects. We find that they get considerable enhancement from the two Higgs doublet m...
b -> s tau(+)tau(-) decay in the two Higgs doublet model with flavor changing neutral currents Iltan, EO; Turan, Gürsevil (2001-06-01) We study the decay width and forward-backward asymmetry of the lepton pair for the inclusive decay b -->s tau (+)tau (-) in the two Higgs doublet model with three level flavor changing neutral currents (model III) and analyze the dependencies of these quantities on the model III parameters, including the leading order QCD corrections. We find that there is a considerable enhancement in the decay width and neutral Higgs effects are detectable for large values of the parameter <(<xi>)over bar>(D)(N,tau tau).
B -> K*l(+)l(-) decay in the two Higgs doublet model with flavor changing neutral currents Alıyev, Tahmasıb (Elsevier BV, 1999-04-01) We study the decay width, forward-backward asymmetry and the longitudinal lepton polarization for the exclusive decay B --> K *l(+)l(-) in the two Higgs doublet model with three level flavor changing neutral currents (model III) and analyse the dependencies of these quantities on the the selected parameters, xi(U,D), of model III including the next to leading QCD corrections. It is found that to look for charged Higgs effects, the measurements of the branching ratio, forward-backward asymmetry and the longi...
B-s ->gamma gamma decay in two and three Higgs doublet models with CP violating effects Boz, M; Iltan, EO (2000-09-01) We analyze the CP asymmetry for B-s-->gamma gamma in the two Higgs doublet model with tree level flavor changing currents (model III) and the three Higgs doublet model with O-2 symmetry in the Higgs sector, including O-7 type long distance effects. Further, we study the dependencies of the branching ratio Br (B-s-->gamma gamma) and the ratio of CP-even and CP-odd amplitude squares, R = \A(+)\(2)/\A(-)\(2), on the CP parameter sin theta. We find that there is a weak CP asymmetry at the order of 10(-4). In ad...
The exclusive B -> (K, K*)l(+)l(-) decays in a CP softly broken two Higgs doublet model Erkol, G; Turan, Gürsevil (2002-07-22) We study the differential branching ratio, forward-backward asymmetry, CP-violating asymmetry, CP-violating asymmetry in the forward-backward asymmetry and polarization asymmetries in the B --> Kl(+)l(-) and B --> K*l(+)l(-) decays in the context of a CP softly broken two Higgs doublet model. We analyze the dependencies of these observables on the model parameters by paying a special attention to the effects of neutral Higgs boson (NHB) exchanges and possible CP-violating effects. We find that NHB effects a...
