Production of P-cs (4459) from Xi(b) Decay

Abstract

Inspired by the P-cs (4459) reported by the LHCb collaboration recently, we investigate the P-cs (4459) production from Xi(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 Xi(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).
