The exclusive B -> K(2)l(+)l(-) decay is studied using the most general, model independent four-fermion interaction. The sensitivity of the ratio of the decay widths when K-2 meson is longitudinally and transversally polarized, the forward-backward asymmetry and longitudinal polarization of the final lepton on the new Wilson coefficients is studied. It is found that these quantities are very useful for establishing new physics beyond the standard model.

Exclusive B -> K*l(+)l(-) decay with polarized K* and new physics effects
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-06-28)
Using the most general, model independent effective Hamiltonian, the branching ratio of the B --> K* l(+)l(-) decay, when K* meson is longitudinally or transversally polarized, is presented. The dependence of the branching ratio on the new Wilson coefficients, when K* meson is polarized. is studied. It is observed that the branching ratio is very sensitive to the vector and tenser type interactions, which will be useful in search of new physics beyond the Standard Model.
B-s ->tau(+)tau(-) decay in the general two Higgs doublet model
Iltan, EO; Turan, Gürsevil (2002-11-01)
We study the exclusive decay B-s --> tau(+)tau(-) in the general two Higgs doublet model. We analyse the dependencies of the branching ratio on the model parameters, including the leading order QCD corrections. We found that there is an enhancement in the branching ratio, especially for r(tb) = (xi) over bar (U)(N,tt)/(xi) over bar (D)(N,bb) > 1 case. Further, the neutral Higgs effects are detectable for large values of the parameter (xi) over bar (D)(N,tautau).
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 -> 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 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).
