Abstract

We estimate the high-energy behavior of the Θ⁺ and Λ(1520) production cross sections in inclusive pp collisions using the K exchange diagram. We show that the cross section of the Θ⁺-production is suppressed compared to the production of Λ(1520). As a byproduct we also estimate the contribution of the π exchange diagram for the inclusive Λ(1520) production in Σp collisions.
