A Measurement of Bottom Quark Production in $p\bar{p}$ Collisions at $\sqrt{s}$ = 1.8-TeV.

Abstract

We present a measurement of the bottom quark production cross section at a center of mass energy of 1.8 TeV in the rapidity region $\mid y \mid$ < 1 and the transverse momentum range 13 to 37 GeV=c. The measurement is extracted from a dataset of 2707 events containing muons and jets, corresponding to an integrated luminosity of $228nb^{-1}$, taken during the 1992-93 collider run of the Tevatron proton-antiproton collider at Fermilab. The measurement is about two standard deviations above QCD predictions, but is consistent with it within measurement uncertainties and uncertainties in the QCD calculation
