A new estimate ofBrightarrow(rho,omega)+gamma in the light-cone QCD sum rule

Abstract
We propose a new estimate of the process B(,)+ by using the light-cone QCD sum rule. The aim is to choose the chiral quark current operators in order to eliminate the uncertainty arising from the chiral-even operators in the correlator. In the case of neglecting the corrections from the -meson mass, the sum rules for form factors are obtained, which are valid to twist-three accuracy. The resulting branching ratios are consistent with the experimental data.
