Abstract

We have measured the production of strange baryons and antibaryons in 340-GeV/c Sigma(-)+C and 260-GeV/c n+C interactions. The single x(F) distributions show the expected leading particle effect, and the single p(t)(2) distributions show a distinct nonthermal behavior. The x(F) distributions of Lambda-Lambda pairs indicate two different phase space distributions for the two coincident baryons. On the other hand two (&ULambda;) over bar 's show identical distributions. Momentum conservation during the formation process may represent a significant source for the observed behavior.
