Measurement of the forward-backward asymmetry of Lambda and (Lambda)over-bar production in p(p)over-bar collisions
Original language description
We study Lambda and (Lambda) over bar production asymmetries in p (p) over bar -> Lambda((Lambda) over bar )X, p (p) over bar -> J/psi Lambda((Lambda) over bar )X, and p (p) over bar -> mu(+/-)Lambda((Lambda) over bar )X events recorded by the D0 detector at the Fermilab Tevatron collider at root s = 1.96 TeV. We find an excess of Lambda's ((Lambda) over bar 's) produced in the proton (antiproton) direction. This forward-backward asymmetry is measured as a function of rapidity. We confirm that the (Lambda) over bar/Lambda 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.
