Abstract

We report a set of measurements of inclusive invariant $p_{T}$ differential cross sections of $Λ^{0}$ , ${\bar{Λ}}^{0}$ , $Ξ^{\pm}$ , and $Ω^{\pm}$ hyperons reconstructed in the central region with pseudorapidity $| η | < 1$ and $p_{T}$ up to $10 GeV / c$ . Events are collected with a minimum-bias trigger in $p \bar{p}$ collisions at a center-of-mass energy of 1.96 TeV using the CDF II detector at the Tevatron Collider. As $p_{T}$ increases, the slopes of the differential cross sections of the three particles are similar, which could indicate a universality of the particle production in $p_{T}$ . The invariant differential cross sections are also presented for different charged-particle multiplicity intervals.

In the CDF coordinate system, $θ$ and $ϕ$ are the polar and azimuthal angles of a track, respectively, defined with respect to the proton beam direction, $z$ . The pseudorapidity $η$ is defined as $- \ln [\tan (θ / 2)]$ . The transverse-momentum of a particle is $p_{T} = p \sin θ$ . The rapidity is defined as $y = 0.5 \ln [(E + p_{z}) / (E - p_{z})]$ , where $E$ and $p_{z}$ are the energy and longitudinal momentum of the particles associated with the track.

The number of $p_{T}$ intervals for data is dictated by statistics such that the fits to the invariant mass distributions are stable. In the acceptance calculation, the number of $p_{T}$ points is chosen such that a smooth acceptance curve as a function of $p_{T}$ can be obtained. The statistical uncertainties of acceptance values are less than a few percent.

The total cross section corresponding to the minimum-bias trigger is estimated to be $45 \pm 8 mb$ . The elastic ( $17 \pm 4 mb$ [19]), single diffractive SD (12 mb), and half of the double diffractive DD (4 mb) cross sections are subtracted from the total $p \bar{p}$ cross section ( $78 \pm 6 mb$ [19, 23]) to give this estimate. The SD and DD cross sections are estimated using pythia [20], and no uncertainties are assigned to SD and DD cross section. A simulation study shows that the minimum-bias trigger is sensitive to $\sim 100 %$ of inelastic events which are not SD or DD and $\sim 50 %$ of DD events. A 100% uncertainty is assigned to the DD contribution attributing to the uncertainty in the event characteristics and detector simulation.
