Abstract: The initial single pion emission (ISPE) mechanism is applied to the processes ϒ(5S)→πB(*)B̄(*), 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*D̄ and D*D̄*.
