The initial single pion emission(ISPE) mechanism is applied to the processes γ(55)→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 one-pion decays of higher charmonia near the thresholds of D*D and D*D*.
