|a We report a measurement of the forward-backward asymmetry, A[subscript FB], in b[bar over b] pairs produced in proton-antiproton collisions and identified by muons from semileptonic b-hadron decays. The event sample is collected at a center-of-mass energy of √s = 1.96 TeV with the CDF II detector and corresponds to 6.9 fb[superscript −1] of integrated luminosity. We obtain an integrated asymmetry of A[subscript FB](b[bar over b])=(1.2± 0.7)% at the particle level for b-quark pairs with invariant mass, m[subscript b[bar over b]], down to 40 GeV/c[superscript 2] and measure the dependence of A[subscript FB](b[bar over b]) on m[subscript b[bar over b]]. The results are compatible with expectations from the standard model.
