从Uponium(5S)到分子Bottomonium的辐射跃迁

Radiative transitions from Upsilon(5S) to molecular bottomonium

M. B. Voloshin

摘要:

重夸克自旋对称性意味着除了最近观察到的与$I^G=1^+$的Z(10610)和Z(10650)分子共振外,还应该存在两个或四个与$I^G=1^-$的分子底偶素类态。这些G-奇态的属性被认为是,包括他们的生产在辐射跃迁从Upperdom(5S),通过应用相同的对称性Upperdom(5S)共振和跃迁振幅。所考虑的辐射过程可以提供一个现实的选择,观察尚未假设的状态。

英文摘要:

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