Study of W-exchange Mode $D^0\to \varphi {\bar{K}}^0$

Abstract

We calculate the branching ratio of $D^0\to \varphi {\bar{K}}^0$ decay using the so-called perturbation QCD approach based on $k_T$ factorization. Our result shows this branching ratio is $(8.7\pm 1.4)\times 10^{-3}$, which is consistent with experimental data. We hope the CLEO-C and BES-III can measure it more accurately, which will help us to understand QCD dynamics and $D$ meson weak decays.
