The authors' main claim We focus on the exotica Z_b(10610), Z_b(10650) and Y_b(10890) in the bottom sector and discuss a possible connection to the exotica in the charm sector, namely to the resonances Y_c(4260) and Z_c(3900).

An overview over recent spectroscopy results in comparison with data is given. We focus on the exotica Z_b(10610), Z_b(10650) and Y_b(10890) in the bottom sector and discuss a possible connection to the exotica in the charm sector, namely to the resonances Y_c(4260) and Z_c(3900). Furthermore, future prospects for the determination of the nature of Y_b(10890) are outlined.

Exotic hadrons: review and perspectives

Richard reviews the exotic hadron landscape sector by sector and argues that double-heavy flavour configurations, not the crowded hidden-charm sector, are the most promising place to find an unambiguous multiquark state.

A community white paper argues that exotic quarkonium spectroscopy and large-transverse-momentum quarkonium production are the two areas where the next decade of experiments will most change our understanding of QCD.
