In the framework of static and QCD-motivated model potentials for heavy quarkonium, we present a further comprehensive calculation of the mass spectrum of bc system and its ground state spin-dependent splittings in the context of the shifted l-expansion technique. We also predict the leptonic constant fB(c), of the lightest pseudoscalar B,, and fB(c)*. of the vector B-c* states taking into account the one-loop and two-loop QCD corrections. Furthermore, we use the scaling relation to predict the leptonic constant of the nS-states of the bc system. Our predicted results are generally in high agreement with some earlier numerical methods. The parameters of each potential are adjusted to obtain best agreement with the experimental spin-averaged data (SAD).

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 -> 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...
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 decays in an asymmetric left-right model Frank, Mariana; Hayreter, Alper; Turan, İsmail (American Physical Society (APS), 2010-08-25) Motivated by recently observed disagreements with the standard model predictions in B decays, we study b -> d, s transitions in an asymmetric class of SU(2)(L) x SU(2)(R) x U(1)(B-L) models, with a simple one-parameter structure of the right-handed mixing matrix for the quarks, which obeys the constraints from kaon physics. We use experimental constraints on the branching ratios of b -> s gamma, b -> ce (nu) over bar (e), and B-d,s(0) - (B) over barB(d,s)(0) mixing to restrict the parameters of the model: g...
Heavy baryon-light vector meson couplings in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-02-15) The strong coupling constants of heavy baryons with light vector mesons are calculated in the framework of the light cone QCD sum rules using the most general form of the interpolating currents for the heavy baryons. It is shown that the sextet sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one invariant function for each class of transitions. The values of the electric and magnetic coupling constants for these transitions are obtained.
