We study the differential branching ratio and CP asymmetry for the exclusive decay B --> K*l(+)l(-) in the three Higgs doublet model with an additional global O(2) symmetry in the Higgs sector. We analyze the dilepton mass square q(2) dependency of these quantities. Further, we study the effect of a new parameter of the global symmetry in the Higgs sector on the differential branching ratio and CP asymmetry. We see that there exists an enhancement in the branching ratio and considerable CP violation for the relevant process. In addition to this, we realize that fixing the dilepton mass gives information about the sign of the Wilson coefficient C-7(eff). Therefore, the future measurements of the CP asymmetry for the B --> K*l(+)l(-) decay will give powerful information about the sign of the Wilson coefficient C-7(eff) and new physics beyond the SM.

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 -> (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...
Rare B->K*l(+)l(-) decay, two Higgs doublet model, and light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (1997-10-02)
The decay width, forward-backward asymmetry and lepton longitudinal and transversal polarization for the exclusive B --> K* l(+)l(-) decay in a two Higgs doublet model are computed. It is shown that all these quantities are very effective tools for establishing new physics. (C) 1997 Elsevier Science B.V.
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.
Exclusive B ->pi l(+)l(-) and B -> pl(+)l(-) decays in the two Higgs doublet model
Alıyev, Tahmasıb (1999-07-01)
We investigate the exclusive B-->pi l(+)l(-) and B-->rho l(+)l(-) decays in the framework of the general two Higgs doublet model (model III), in which an extra phase angle in the charged-Higes fermion coupling, i.e., a new source for CP violation, exists. The CP violation for both decays is calculated and it is observed that the CP-violating asymmetry in model III differs significantly from the one predicted by the standard model and model II which is a special case of model III. Furthermore, it is shown th...
