Measurement of b(b)over-bar rapidity correlations in p(p)over-bar collisions at root s=1.8 TeV

We report the first direct measurement of <b(b)over bar> rapidity correlations in <p(p)over bar> collisions at root 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 pp interaction vertex. Two independent samples are obtained corresponding to events with a forward (2.0<\eta\<2.6) or central (\eta\<0.6) muon. We measure the ratio of forward to central <b(b)over bar> 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).
