Abstract

The heavy quark spin symmetry implies that in addition to the recently observed Z(10610) and Z(10650) molecular resonances with IG=1+, there should exist two or four molecular bottomonium-like states with IG=1 -. Properties of these G-odd states are considered, including their production in the radiative transitions from Υ(5S), by applying the same symmetry to the Υ(5S) resonance and the transition amplitudes. The considered radiative processes can provide a realistic option for observing the yet hypothetical states.
