摘      要：The initial single pion emission （ISPE） mechanism is applied to the processes r（5S）→πB（＊）B-（＊）, whose details have been recently reported at ICHEP2012, and we obtain reasonable agreement with Bell＇s measurements; that is, we succeed in reproducing the enhancement structures of Zb（10610） and Zb（10650）. Inspired by this success, we also predict the corresponding enhancement structures in open charm oue-pion decays of higher charmonia near the thresholds of D＊D- and D＊D-＊.
