Measurement of the ratio of b quark production cross sections in (p)over-bar-p collisions at root s=630 GeV and root s=1800 GeV

Measurement of the ratio of b quark production cross sections in (p)over-bar-p collisions at root s=630 GeV and root s=1800 GeV

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)/...
