Composite nature of $$Z_b$$ Z b states from data analysis
Abstract We use a near-threshold parameterization with explicit inclusion of the Castillejo–Dalitz–Dyson poles, which is more general than the effective range expansion, to study the bottomonium-like states $$Z_b(10610)$$ Z b ( 10610 ) and $$Z_b(10650)$$ Z b ( 10650 ) . In terms of the partial-wave...
