Production of Pcs (4459) from Ξb Decay

Abstract

Inspired by the P_cs (4459) reported by the LHCb collaboration recently, we investigate the P_cs (4459) production from Ξ_b decay in a molecular scenario using an effective Lagrangian approach. With different J^P assignments to P_cs (4459), the magnitude of branching fractions of Ξ_b → P_cs (4459) K is estimated, which is of the order of 10⁻⁴. Together with the decay properties of P_cs (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 J^P quantum numbers of P_cs (4459).
