Title: Hadro-quarkonia dynamics and Z{sub b} states

Dynamics of hadro-quarkonium system is formulated, based on the channel coupling of a light hadron (h) and heavy quarkonium (QQ-bar) to heavy-light mesons (Qq-bar, Q-barq). Equations for hadro-quarkonium amplitudes and resonance positions are written explicitly, and numerically calculated for the special case of {pi} Greek-Upsilon-With-Hook-Symbol (nS) (n = 1, 2, 3). It is also shown that the recently observed by Belle two peaks Z{sub b}(10610) and Z{sub b}(10650) are in agreement with the proposed theory. It is demonstrated that theory predicts peaks at the BB*, B*B* thresholds in all available {pi} Greek-Upsilon-With-Hook-Symbol (nS) channels.
