Abstract

We report on measurements of correlated {Mathematical expression} production in {Mathematical expression} collisions at {Mathematical expression}, using dimuon data to tag both the b and {Mathematical expression} quarks. Starting from an inclusive dimuon sample we obtain improved cross-sections for single inclusive beauty production and confirm our earlier results on {Mathematical expression} mixing. From a study of {Mathematical expression} correlations we derive explicit cross-sections for semi-differential {Mathematical expression} production. We compare the measured cross-sections and correlations to {Mathematical expression} QCD predictions and find good quantitative agreement. From the measured angular distributions we establish a size-able contribution from higher order QCD processes with a significance of about seven standard deviations. A large nonperturbative contribution to these higher order corrections is excluded.
