Abstract

We measure the forward-backward asymmetry in the production of Λb0 and Λ¯b0 baryons as a function of rapidity in pp¯ collisions at s=1.96TeV using 10.4fb-1 of data collected with the D0 detector at the Fermilab Tevatron collider. The asymmetry is determined by the preference of Λb0 or Λ¯b0 particles to be produced in the direction of the beam protons or antiprotons, respectively. The measured asymmetry integrated over rapidity y in the range 0.1<|y|<2.0 is A=0.04±0.07(stat)±0.02(syst).
