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 ...
Possible molecular pentaquark states with different spin and quark configurations
(American Physical Society, 2018-09)
We investigate three possible pentaquark candidates, one of which contains a single charm quark and the other two contain triple charm quarks in their substructure. To this end we apply the QCD sum rule method and take ...
