Factorization in the inclusive reactions pp → Λ + X ++ and K +p → Λ + X ++

Abstract

A test of factorization is made using data on the inclusive reactions pp → Λ + X ++ at 19 GeV/ c and K +p → Λ + X ++ at 16 GeV/ c incident momentum. In these reactions Λ production occurs dominantly via proton fragmentation and, in addition, ab c is exotic in both cases. The comparison of the structure functions on the Chew-Low plot shows that the factorization hypothesis is satisfied at the ∼10% level when the momentum transfer from the proton to the Λ is less than 1 (GeV/ c) 2.
