Spectra and correlations of Λ and Λ̄ produced in 340-GeV/c Σ- C and 260-GeV/c n C interactions Article uri icon

abstract

  • We have measured the production of strange baryons and antibaryons in 340-GeV/c Σ- C and 260-GeV/c n C interactions. The single xF distributions show the expected leading particle effect, and the single pt2 distributions show a distinct nonthermal behavior. The xF distributions of Λ-Λ pairs indicate two different phase space distributions for the two coincident baryons. On the other hand two Λ̄s show identical distributions. Momentum conservation during the formation process may represent a significant source for the observed behavior.
