The branching ratio, forward-backward asymmetry and CP violating asymmetry for B --> X(d)l(+)l(-) decay, in framework of the general two Higgs doublet model, with extra phase angle in the charged-Hwiggs-fermion coupling, are calculated. It is shown that studying the CP violating asymmetry is an efficient tool for establishing new physics.

The gV sigma gamma coupling constants in hadron electrodynamics Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2003-09-22) Recent measurements of the branching ratios for the decays omega --> pi(0) pi(0)gamma and rho(0) --> pi(0)pi(0)gamma lead to coupling constants of the Vsigmagamma interaction (V is a vector meson) one order of magnitude smaller than previously assumed to describe the threshold cross section of gamma + p --> p + rho(0) and the HERMES effect. The new g(Vsigmagamma)(2) a couplings are in contradiction with the predictions of the QCD sum rules, but are in agreement with vector meson dominance estimation of the ...
CP violation in the radiative dileptonic B-meson decays Erkol, G; Turan, Gürsevil (IOP Publishing, 2002-12-01) We investigate the CP violating asymmetry, the forward-backward asymmetry and the CP violating asymmetry in the forward-backward asymmetry for the radiative dileptonic B-meson decays B-d --> gammal(+)l(-) for the f = e, mu, tau channels. It is observed that these asymmetries are quite sizable and B-d --> gamma l(+)l(-) decays seem promising for investigating CP violation.
Standard model CP violation in B -> X(d)l(+)l(-) decays Eygi, ZD; Turan, Gürsevil (World Scientific Pub Co Pte Lt, 2003-12-14) We investigate the CP violating asymmetry, the forward backward asymmetry and the CP violating asymmetry in the forward-backward asymmetry for the inclusive B --> X(d)l(+)l(-) decays for the l = e, mu, tau channels in the standard model. It is observed that these asymmetries are quite sizeable and B --> X(d)l(+)l(-) decays seem promising for investigating CP violation.
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...
Analysis of exclusive B-s -> D-s0(2317)l(v)over-bar(e) decay with QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2006-06-01) The transition form factors of the semileptonic decay B-s into scalar D-s0(2317) meson is calculated in the framework of 3-point QCD sum rule. The branching ratio is found to be similar to 10(-3) for the B-s -> D-s0(2317)center dot(v) over bar (center dot)(center dot=e,mu) decay, and similar to 10(-4) for the B-s -> D-s0(2317)tau(v) over bar (tau) decay, respectively.
