Measurement of the forward-backward asymmetry of Λ and Λ production in pp collisions
Original language description
We study Λ and Λ production asymmetries in ppΛ(Λ)X, ppJ/ψΛ(Λ)X, and ppμΛ(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.n
