We study phia(0)gamma- and phisigmagamma-vertices in the framework of the light cone QCD sum rules and we estimate the coupling constants gphia(0)gamma and gphisigmagamma utilizing omega-phi mixing. We compare our results with the previous estimations of these coupling constants in the literature obtained from phenomenological considerations.

THE EFFECT OF LOCALIZED NEW HIGGS DOUBLET ON THE RADIATIVE LEPTON FLAVOR VIOLATING DECAYS IN THE RANDALL SUNDRUM BACKGROUND Iltan, E. O. (2010-03-01) We study the radiative lepton-flavor violating l(1) -> l(2)gamma decays in the two Higgs doublet model with localized new Higgs doublet in the Randall Sundrum background. We estimate the contributions of the KK modes of new Higgs bosons and left (right) handed charged lepton doublets (singlets) on the branching ratios of the decays considered. We observe that there is an enhancement in the branching ratios with the addition of new Higgs boson and lepton KK modes.
The decay rho(0) -> pi(0)pi(0)gamma and the role of sigma-meson Gokalp, A; Yılmaz, Osman (2001-05-24) We study the radiative decay p(0) --> pi (0)pi (0)gamma within the framework of a phenomenological approach in which the contributions of sigma -meson and omega -meson intermediate states and of the pion-loops are considered. We conclude that the sigma -meson amplitude makes a substantial contribution.
The coupling constants g(rho pi gamma) and g(omega pi gamma) as derived from QCD sum rules Gokalp, A; Yılmaz, Osman (2002-05-01) We employ QCD sum rules to calculate the coupling constants g(rhopigamma) and g(rhopigamma) by studying the three point rhopigamma and omegapigamma correlation functions. Our results are in good agreement with the coupling constants g(rhopigamma) and g(omegapigamma) that are deduced utilizing the experimentally measured values of the Gamma(rho(0) --> pi(0)gamma) and Gamma(omega --> pi(0)gamma) decay widths.
The mu -> e gamma and tau ->mu gamma decays in the general two Higgs doublet model with the inclusion of one universal extra dimension Iltan, EO (2004-02-01) We study the effect of one universal extra dimension on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these new effects are tiny for the small values of the compactification radius R. Furthermore, we see that these effects are comparable with the branching ratio obtained without including extra dimension, if the neutral Higgs bosons are nearly degenerate and the complexity of the Yukawa coupling, induci...
Strong Coupling Constants of Heavy Baryons With Light Mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2012-06-21) The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
