Abstract
Inspired by the Pcs (4459) reported by the LHCb collaboration recently, we investigate the Pcs (4459) production from Ξb decay in a molecular scenario using an effective Lagrangian approach. With different JP assignments to Pcs (4459), the magnitude of branching fractions of Ξb → Pcs (4459) K is estimated, which is of the order of 10-4. Together with the decay properties of Pcs (4459), the present estimations could be further testified by precise measurements and contribute to a better understanding of the molecular interpretations and the exploration of JP quantum numbers of Pcs (4459).
