Abstract

We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at s√=630 GeV to 1800 GeV using bottom quarks with transverse momenta greater than 10.75 GeV identified through their semileptonic decays and long lifetimes. The measured ratio σ(630)/σ(1800)=0.171±.024±.012 is in good agreement with next-to-leading order quantum chromodynamics.
