We report on measurements of differential μ-b¯ cross sections, where the muon is from a semileptonic b decay and the b¯ is identified using precision track reconstruction in jets. The semidifferential correlated cross sections dσ/${\mathit{dE}}_{\mathit{T}}^{\mathit{b}\mathrm{¯}}$, dσ/${\mathit{dp}}_{\mathit{T}}^{\mathit{b}\mathrm{¯}}$, and dσ/dδφ(μ-b¯) for ${\mathit{p}}_{\mathit{T}}^{\mathrm{\mu }}$≳9 GeV/c, ‖${\mathrm{\eta }}^{\mathrm{\mu }}$‖〈0.6,${\mathit{E}}_{\mathit{T}}^{\mathit{b}\mathrm{¯}}$〉 10 GeV, ‖${\mathrm{\eta }}^{\mathit{b}\mathrm{¯}}$‖<1.5 are presented and compared to next-to-leading order QCD calculations. © 1996 The American Physical Society.
