Interpretation of Zb(10610) and Zb(10650) in the ISPE mechanism and the Charmonium Counterpart
2014
The initial single pion emission (ISPE) mechanism is applied to the processes Y(5S)→πB (∗) ¯ B (∗) ,w hose 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 ∗ ¯ Da nd D ∗ ¯ D ∗ .
