A New Estimate of B→(ρ,ω)+γ In The Light-Cone QCD Sum Rule
Abstract
We propose a new estimate of the process
B→(ρ,ω)+γ
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
ρ
-meson mass, the sum rules for form factors are obtained, which are valid to the twist-three accuracy. The resulting branching ratios are consistent with the experimental data.
