We calculate the leading logarithmic QCD corrections to the decay B-s --> gamma gamma in the two Higgs doublet model with tree level flavor changing currents (modeI III) including O-7 type long distance effects. Further, we analyze the dependences of the branching ratio B(B-s --> gamma gamma) and the ratio of CP-even and CP-odd amplitude squares, R = \A(+)\(2)/\A(-)\(2), on the charged Higgs boson mass m(H+/-) and the selected model III parameters xi(U,D) including the leading logarithmic QCD corrections. It is found that the measurement of the branching ratio B(B-s --> gamma gamma) is promising to search charged Higgs effects. [S0556-2821(98)09121-8]

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...
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-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 gamma decay in the two Higgs doublet model with flavour changing neutral currents
Alıyev, Tahmasıb (IOP Publishing, 1999-05-01)
We study the b --> s gamma decay including the next-to-leading QCD corrections in the two Higgs doublet model with flavour changing neutral currents at the tree level. We find the constraints to the flavour changing parameters of the model, using the experimental results on the branching ratio of B --> X(s)gamma decay, provided by the CLEO Collaboration. The restrictions coming from the Delta F = 2 (F = K, D, B) mixing and the rho parameter.
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...
