title = "Measurement of the forward-backward asymmetry of Λ and Λ ¯ production in p p ¯ collisions",
abstract = "We study Λ and Λ¯ production asymmetries in pp¯→Λ(Λ¯)X, pp¯→J/ψΛ(Λ¯)X, and pp¯→μ±Λ(Λ¯)X events recorded by the D0 detector at the Fermilab Tevatron collider at s=1.96 TeV. We find an excess of Λ's (Λ¯'s) produced in the proton (antiproton) direction. This forward-backward asymmetry is measured as a function of rapidity. We confirm that the Λ¯/Λ production ratio, measured by several experiments with various targets and a wide range of energies, is a universal function of {"}rapidity loss,{"} i.e., the rapidity difference of the beam proton and the lambda.",
