Inclusive pentaquark and strange baryons production in hadron beam experiments at high energy

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.
