Abstract

Abstract In this article, we calculate the contribution from the nonfactorizable soft hadronic matrix element to the decay

B^{0} \to χ_{c 1} π^{0}

with the light-cone quantum chromo-dynamic (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.

Keywords: light-cone QCD sum rule B-decay nonfactorizable hadronic matrix element
