Description
Assuming a molecular nature for the $Z_b(10610)$ and $Z_b(10650)$ exotic states, the properties of these states and their pole positions are extracted from the effective-field theory based analysis of the experimental line shapes in the decay channels $\Upsilon(10860) \to \pi \alpha$ (with $\alpha$ being $B\bar B^*, B^*\bar B^*$ and $h_b (mP)\pi$ ($m$=1,2)). The consequences for the heavy-quark spin-symmetry partners of these states are predicted parameter free.
