Dynamics of hadro-quarkonium system is formulated, based on the channel coupling of a light hadron (h) and heavy quarkonium <##> $\}\left(\}Q\}\stackrel{\}¯}{Q}\right)$$$ /left( {Q/bar Q} /right) $$(Q Q-bar ) to heavy-light mesons (<##> $\}{Q}_{\}\}\stackrel{\}¯}{q}}$$$ Q{sub {/bar q}} $$Q{sub q-bar }, <##> $\}{\}\stackrel{\}¯}{Q}}_q$$$ /bar Q{sub q} $$ Q-bar {sub q}). Equations for hadro-quarkonium amplitudes and resonance positions are written explicitly, and numerically calculated for the special case of πϒ(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 πϒ(nS) channels.
