چکیده
The φa 0 γ-and φσγ-vertices in light cone QCD Abstract We study φa 0 γ-and φσγ-vertices in the framework of the light cone QCD sum rules and we estimate the coupling constants g φa 0 γ and g φσγ utilizing ωφ-mixing. We compare our results with the previous estimations of these coupling constants in the literature obtained from phenomenological considerations .

We have analyzed the B → π and Bs → K semileptonic form factors and B → V γ(V = K, ρ, ω) processes in the light-cone QCD sum rules. In order to enhance the predictivity and reliability of numerical results the chiral-current correlator is employed and the twist-3 light-cone wavefunction can be effectively eliminated from the sum rules.
