Abstract
We report on measurements of correlated bbBAR production in ppBAR coll isions at square-root s = 630 GeV, using dimuon data to tag both the b and bBAR quarks. Starting from an inclusive dimuon sample we obtain i mproved cross-sections for single inclusive beauty production and conf irm our earlier results on B0-B0BAR mixing. From a study of bbBAR corr elations we derive explicit cross-sections for semi-differential bbBAR production. We compare the measured cross-sections and correlations t o O(alpha(s)3) QCD predictions and find good quantitative agreement. F rom the measured angular distributions we establish a sizeable contrib ution from higher order QCD processes with a significance of about sev en standard deviations. A large nonperturbative contribution to these higher order corrections is excluded.
