Title: Measurement of the forward-backward asymmetry in Λ b 0 and $$\bar{Λ}_b^0$$ baryon production in $$p\bar{p}$$ collisions at $$\sqrt{s}$$=1.96 TeV

Abstract

We measure the forward-backward asymmetry in the production of Λ 0 b and Λ ¯0 b baryons as a function of rapidity in pp¯ collisions at √s = 1.96 TeV using 10.4 fb -1 of data collected with the D0 detector at the Fermilab Tevatron collider. The asymmetry is determined by the preference of Λ 0 b or Λ ¯0 b particles to be produced in the direction of the beam protons or antiprotons, respectively. As a result, 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).
