The production of the hidden-charm pentaquark P-cs(0),(4459) with strangeness in the K- p -> J/Psi Lambda reaction was investigated using two theoretical frameworks, and the total and differential cross sections were computed. The contributions of P-cs with different sets of spin-parity quantum number assigned were examined, providing a guide for possible future experiments.
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.
