Production of P_(cs) (4459) from Ξ_b Decay

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).
