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

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, abantic 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 approximately 10 % level when the momentum transfer from the proton to the Λ is less than 1 (GeV/c)2.
