Analysis of the decay with light-cone QCD sum rules
Abstract
In this article, we calculate the contribution from the nonfactorizable soft hadronic matrix element to the decay with the light-cone QCD sum rules. The numerical results show that its contribution is rather large and should not be neglected. The total amplitudes lead to a branching fraction which is in agreement with the experimental data marginally.
