Hyperon production in proton-lead and lead-lead collisions at 158 GeV/c per nucleon
The WA97 experiment studies the production of strange and multistrange particles in Pb−Pb and p−Pb collisions at 158 GeV/c per nucleon. Recent results on ≡ and ω production ratios and transverse mass distributions are reported and compared with those obtained by WA85 and WA94 experiments. A significant enhancement of the ω/≡ ratio has been observed when going from nucleon-Nucleus to Nucleus-Nucleus reactions.
