Spin partners of the Z b (10610) and Z b (10650) revisited

Spin partners of the Z b (10610) and Z b (10650) revisited

Abstract We study the implications of the heavy-quark spin symmetry for the possible spin partners of the exotic states Z b (10610) and Z b (10650) in the spectrum of bottomonium. We formulate and solve numerically the coupled-channel equations for the Z b states that allow for a dynamical generatio...
