High Energy Physics - Phenomenology 2009-10-30 v2

Abstract

We discuss the nonfactorization effects in BJ/Ψ+XsB\to J/\Psi+X_{s}, which is similar to the nonperturbative effect found by Voloshin in the decay Bγ+XsB\to \gamma +X_{s}. The QCD sum rule has been used to estimate the hadron matrix elements. We find that the correction from this effect is very large and the large discrepancy between the theory and the experimental data can be reduced considerably.
