Abstract
We calculate [Formula: see text] translation form factors [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] based on QCD sum rule and study the nonleptonic two-body decay of [Formula: see text] with the form factors obtained. We calculate the time-integrated branching ratio of [Formula: see text] decay. The results for both the total branching ratio and the cases for the final vectors in longitudinal and transverse polarizations are consistent with experimental data.
