Hyperon production from proton-antiproton collisions at radical s =1. 8 TeV

The production properties of lambdas ({Lambda}{sup 0},{bar {Lambda}} {sup 0}) and cascades ({Xi}{sup {minus}},{bar {Xi}} {sup {minus}}) in the central region in {ital {bar p}p} collisions at {radical}{ital s} =1.8 TeV at the Fermilab collider are reported. The transverse-momentum spectra of lambdas...

Zusammenfassung:	The production properties of lambdas ({Lambda}{sup 0},{bar {Lambda}} {sup 0}) and cascades ({Xi}{sup {minus}},{bar {Xi}} {sup {minus}}) in the central region in {ital {bar p}p} collisions at {radical}{ital s} =1.8 TeV at the Fermilab collider are reported. The transverse-momentum spectra of lambdas are measured as a function of multiplicity and the ratios of lambdas to protons ({ital p},{ital {bar p}}) and to all charged particles are studied as a function of transverse momentum and multiplicity. Moreover the average transverse momentum of cascades and the ratio of cascades to lambdas are presented.
