We present bound state masses of the self-conjugate and non-self-conjugate mesons in the context of the Schrodinger equation taking into account the relativistic kinematics and the quark spins. We apply the usual interaction by adding the spin dependent correction. The hyperfine splittings for the 2S charmonium and 1S bottomonium are calculated. The pseudoscalar and vector decay constants of the B-c meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local equation with a complete relativistic corrections to a class of three attractive static interaction potentials of the general form V(r) = -Ar-beta + kappa r(-beta) + V-0, with beta = 1, 1/2, 3/4 which can also be decomposed into scalar and vector parts in the form V-V(r) = -Ar-beta + (1 - epsilon)kappa r(beta) and V-S(r) = epsilon kappa r(beta) + V-0; where 0 <= epsilon <= 1. The energy eigenvalues are carried out up to the third order approximation using the shifted large-N-expansion technique.

Mass spectra of heavy quarkonia and B-c decay constant for static scalar-vector interactions with relativistic kinematics Ikhdair, SM; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2005-11-10) We reproduce masses of the self-conjugate and non-self-conjugate mesons in the context of the spinless Salpeter equation taking into account the relativistic kinematics and the quark spins. The hyperfine splittings for the 2S charmonium and IS bottomonium are also calculated. Further, the pseudoscalar and vector decay constants of the Be meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local equation with a complete relativistic corrections to a class of t...
SENSITIVITY OF THE STOKES PARAMETERS IN THE DECAY B-]S-GAMMA-G TO THE MODEL OF FCNC Alıyev, Tahmasıb; TURAN, G (Springer Science and Business Media LLC, 1995-01-01) We calculated the Stokes parameters which characterize the polarization properties of the photons produced in the decay b-->s gamma g in the framework of the Standard Model (SM) and Two Higgs Doublet Model (2HDM). It is shown that the Stokes parameter xi 3, which defines the linear photon polarization with a polarization vector in the decay plane, is very sensitive to the parameters of the above-mentioned models. The predicted values of xi(3) are large enough (in some cases it achieves the maximum possible ...
The exclusive (B)over-bar ->pi e(+)e(-) and (B)over-bar ->rho e(+)e(-) decays in the two Higgs doublet model with flavor changing neutral currents Iltan, EO (World Scientific Pub Co Pte Lt, 1999-10-30) We present the leading logarithmic QCD corrections to the matrix element of the decay b --> de(+)e(-) in the two Higgs doublet model with tree level flavor changing currents (model III). We continue studying the differential branching ratio and the CP-violating asymmetry for the exclusive decays B --> pi e(+)e(-) and B --> pe(+)e(-) and analysing the dependencies of these quantities on the selected model III parameters, xi(U,D), including the leading logarithmic QCD corrections. Further, we present the forw...
Moller energy-momentum prescription for a Locally Rotationally Symmetric space-time Aydogdu, Oktay (World Scientific Pub Co Pte Lt, 2006-07-20) The energy distribution in the Locally Rotationally Symmetric (LRS) Bianchi type II space-time is obtained by considering the Mauler energy-momentum definition in both Einstein's theory of general relativity and teleparallel theory of relativity. The energy distribution which includes both the matter and gravitational field is found to be zero in both of these different gravitation theories. This result agrees with previous works of Cooperstock and Israelit, Rosen, Johri et al., Banerjee and Sen, Vargas, an...
Topological black holes and momentum four-vector Pirinccioglu, Nurettin; Binbay, Figen; AÇIKGÖZ, İRFAN; Aydogdu, Oktay (World Scientific Pub Co Pte Lt, 2007-07-30) We consider the energy momentum definition of the Moller in both general relativity and teleparallel gravity to evaluate the energy distribution (due to both matter and fields including gravitation) associated with the topological black holes with a conformally coupled scalar field. Our results show that the energy depends on the mass M and charge Q of the black holes and cosmological constant Lambda. In some special limits, the expression of the energy reduces to the energy of the well-known spacetimes. Th...
