We investigate the omegasigmagamma-vertex and estimate the coupling constant g(omegasigmagamma) in the framework of the light cone QCD sum rules. We compare our result with the values of this coupling constant deduced from a phenomenological analysis of omega --> pipigamma decays.

The mass and residues of radially and orbitally excited doubly heavy baryons in QCD
Alıyev, Tahmasıb; Bilmiş, Selçuk (Elsevier BV, 2019-04-01)
The mass and residues of the first radial and orbital excitations of J = 1/2 baryons containing two heavy quarks (b or c) are calculated within the QCD sum rules method. In calculations, the general forms of the interpolating currents with symmetric and anti-symmetric forms with respect to the exchange of heavy quarks have been used. Our results on the spectroscopic parameters of doubly heavy baryons are compared with the predictions of other theoretical approaches.
Analysis of Radial Excitations of Octet Baryons in QCD Sum Rules
Alıyev, Tahmasıb; Bilmiş, Selçuk (Hindawi Limited, 2017-01-01)
Using the QCD sum rules method, we estimate the mass and residues of the first radial excitations of octet baryons. The contributions coming from the ground state baryons are eliminated by constructing the linear combinations of the sum rules corresponding to different Lorentz structures. Our predictions of the masses of the first radial excitations of octet baryons are in good agreement with the data.
The semileptonic B to K-1(1270,1400) decays in QCD sum rules
Dag, H.; Özpineci, Altuğ; Zeyrek, Mehmet Tevfik (IOP Publishing, 2011-01-01)
We analyze the semileptonic rare decays of the B meson to K-1(1270) and K-1(1400) axial vector mesons. The B -> K-1(1270, 1400)l(+)l(-) decays are significant flavor-changing neutral current decays of the B meson. These decays are sensitive to the new physics beyond the standard model (SM), since these processes are forbidden at tree level at SM. These decays occurring at the quark level via b -> sl(+)l(-) transition also provide new opportunities for calculating the CKM matrix elements V-bt and V-ts. In th...
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 ...
Delta pi N coupling constant in light come QCD sum rules
Gokalp, A; Yılmaz, Osman (IOP Publishing, 1999-12-01)
We employ the light cone QCD sum rules to calculate Delta pi N coupling constant by studying the two-point correlation function between the vacuum and the pion state. Our result is consistent with the traditional QCD sum rules calculations and it is in agreement with the experimental value.
