We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at [Formula Presented] 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 [Formula Presented] is in good agreement with next-to-leading order quantum chromodynamics.

Abstract
We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at [Formula Presented] 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 [Formula Presented] is in good agreement with next-to-leading order quantum chromodynamics.File in questo prodotto:
