Measurement of correlated $μ- {overline b}$ jet cross sections in $p {\bar p}$ collisions at $\sqrt{s}=1.8$ TeV

Abstract

We report on measurements of differential $μ- {\bar b}$ cross sections, where the muon is from a semi-leptonic $b$ decay and the ${\bar b}$ is identified using precision track reconstruction in jets. The semi-differential correlated cross sections, d$σ$/d$\Et^{\bar b}$, d$σ$/d$\pt^{\bar b}$, and d$σ$/d$δϕ(μ- {\bar b})$ for $\pt^μ>$~9 GeV/c, $|η^μ|<$~0.6, $\Et^{\bar b}>$~10 GeV, $|η^{\bar b}|<$~1.5, are presented and compared to next-to-leading order QCD calculations.
