Importance of Higher Twist Effects to Understand Charmed Color-Suppressed $B$ Decays

Zuo-Hong Li, Zhong-Qian Su, Jian-Ying Cui

Working within the framework of the QCD light cone sum rules (LCSR), we compute and discuss the nonfactorizable higher twist effect in ${\bar{B}}^0\to D^{\ast 0}{\pi }^0$ to make an all-aroun…
