Structure of the Ξb (6227)- resonance
(American Physical Society, 2018)
We explore the recently observed Ξbð6227Þ− resonance to fix its quantum numbers. To this end, we consider various possible scenarios: It can be considered as either a 1P or 2S excitation of the Ξ−b and Ξ0bð5935Þ ground-state ...
