Production of hidden-charm strange pentaquarks Pcs from the K- p → J/ΨΛ reaction

We investigate the production of the hidden-charm pentaquark P-cs(0),(4459) with strangeness in the K- p -> J/Psi Lambda reaction, employing two different theoretical frameworks, i.e., the effective Lagrangian method and the Regge approach. Having determined all relevant coupling constants, we are able to compute the total and differential cross sections for the K- p -> J/Psi Lambda reaction. We examine the contributions of P-cs with different sets of spin-parity quantum number assigned. The present results may give a guide for possible future experiments.
