Description:
Author(s): Xian-Wei Kang, Zhi-Hui Guo, and J. A. Oller The nature of the bottomonium-like states Z b ( 10610 ) and Z b ( 10650 ) is studied by calculating the B ( * ) B ¯ * compositeness ( X ) in those resonances. We first consider uncoupled isovector S -wave scattering of B ( * ) B ¯ * within the framework of effective-range expansion (ERE). Expressions for the scattering le… [Phys. Rev.
