Abstract

Measurements of inclusive transverse-momentum spectra for

K_{S}^{0}

mesons produced in proton-antiproton collisions at

\sqrt{s}

of 630 and 1800 GeV are presented and compared with data taken at lower energies. The ratio, as a function of

p_{T}

, of the cross section for

K_{S}^{0}

to that for charged hadrons is very similar to what is observed at lower energies. At 1800 GeV, we calculate the strangeness-suppression factor

λ = 0.40 \pm 0.05

.
