Production of P_(cs)(4459) fromΞ_(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 JP 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 JP quantum numbers of P_(cs)(4459).
