Strange particle production in proton-antiproton collisions at center-of-mass energies of 630 GeV and 1800 GeV
Abstract
The inclusive production of the strange particles $K\sbsp {s}{0}$ and $\Lambda$ has been studied in proton-antiproton collisions at $\sqrt{s}$ = 630 GeV and $\sqrt{s} = 1800$ GeV. The inclusive invariant cross-sections, as functions of transverse momentum $(p\sb{T})$, are presented for their production in minimum-bias events. The ratio, as a function of $p\sb{T}$, of the cross-section for $K\sbsp {s}{0}$ to that for charged hadrons is very similar to what is observed at lower energies. At 1800 GeV, we estimate the strangeness-suppression factor $\lambda = 0.38 \pm 0.06$.
