Interpretation of $Z_b(10610)$ and $Z_b(10650)$ in the ISPE mechanism
and the Charmonium Counterpart    [PDF]

The initial single pion emission (ISPE) mechanism is applied to the processes $\Upsilon(5S)\to \pi B^{(*)}\bar{B}^{(*)}$ whose details have been recently reported at ICHEP2012 and we obtain reasonable agreement with Bell's measurements, i.e., we succeed in reproducing the enhancement structures of $Z_b(10610)$ and $Z_b(10650)$. Inspired by this success, we predict the corresponding enhancement structures in higher charmonia open charm pion decay near the thresholds of $D^\ast \bar{D}$ and $D^\ast \bar{D}^\ast$.
