We study the differential branching ratio, forward-backward asymmetry, CP violating asymmetry, CP violating asymmetry in the forward-backward asymmetry and polarization asymmetries of the final lepton in the B --> X(d)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 are quite significant for the T mode. The above-mentioned observables seems to be promising as a testing ground for new physics beyond the SM, especially for the existence of the CP violating phase in the theory.

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*tau(+)tau(-) decay in the general two Higgs doublet model including the neutral Higgs boson effects Iltan, EO; Turan, Gürsevil; Turan, İsmail (IOP Publishing, 2002-02-01) We study the CP violating asymmetry, the forward-backward asymmetry of the lepton pair and the CP asymmetry in the forward-backward asymmetry for the exclusive decay B --> K*tau(+)tau(-) in the general two Higgs doublet model including the neutral Higgs boson effects. We analyse the dependences of these quantities on the model III parameters. We found that the physical parameters studied above are of the order of 1%, and neutral Higgs boson effects are detectable for large values of the coupling (ξ) over...
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...
B SG decay in the framework of multi Higgs doublet models including QCD corrections Solmaz, Levent; İltan, Erhan Onur; Department of Physics (2002) 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...
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...
