Exotic Heavy Quark Spectroscopy - Theory Interpretation vs Data
Abstract
An overview over recent spectroscopy results in comparison with data is given. We focus on the exotica Zb(10610), Zb(10650) and Yb(10890) in the bottom sector and discuss a possible connection to the exotica in the charm sector, namely to the resonances Yc(4260) and Zc(3900). Furthermore, future prospects for the determination of the nature of Yb(10890) are outlined.
