Abstract

We report the first direct measurement of bb̅ rapidity correlations in pp̅ collisions at √s =1.8 TeV. We select events with a high transverse momentum muon accompanied by a jet, and a second jet associated with a decay vertex displaced from the pp̅ interaction vertex. Two independent samples are obtained corresponding to events with a forward (2.0<|η|bb̅ production to be 0.361±0.033(stat) _-0.031^+0.015(syst), in good agreement with the next-to-leading order QCD prediction 0.338_-0.097^+0.014
