Measurement of bottom quark production in 1.8 TeV<i>pp¯</i>collisions using muons from<i>b</i>-quark decays

Abstract

We present a measurement of the b-quark cross section in 1.8 TeV p-p\ifmmode\bar\else\textasciimacron\fi{} collisions recorded with the Collider Detector at Fermilab using muonic b-quark decays. In the central rapidity region (\ensuremath{\Vert}${\mathit{y}}^{\mathit{b}}$\ensuremath{\Vert}1.0), the cross section is 295\ifmmode\pm\else\textpm\fi{}21\ifmmode\pm\else\textpm\fi{}75 nb (59\ifmmode\pm\else\textpm\fi{}14\ifmmode\pm\else\textpm\fi{}15 nb) for ${\mathit{p}}_{\mathit{T}}^{\mathit{b}}$&gt;21 GeV/c (29 GeV/c). Comparisons are made to previous measurements and next-to-leading order QCD calculations.
