We report a set of measurements of inclusive invariant pT
differential cross sections of Λ0, Λ̅ 0, Ξ±, and Ω± hyperons
reconstructed in the central region with pseudorapi+dity |η|<1 and
pT up to 10 GeV/c. Events are collected with a minimum-bias trigger
in pp̅ collisions at a center-of-mass energy of 1.96 TeV using the
CDF II detector at the Tevatron Collider. As pT increases, the slopes
of the differential cross sections of the three particles are similar,
which could indicate a universality of the particle production in pT. The
invariant differential cross sections are also presented for different
charged-particle multiplicity intervals.
