Production of Λ0, Λ ̄0, Ξ ±, and Ω± hyperons in pp̄ collisions at √s=1.96TeV

Journal article

We report a set of measurements of inclusive invariant p T differential cross sections of Λ0, Λ ̄0, Ξ ±, and Ω ± hyperons reconstructed in the central region with pseudorapidity |η|<1 and p T up to 10GeV/c. Events are collected with a minimum-bias trigger in pp̄ 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 univer...
