Measurement of bb̄ production correlations, B0B̄0 mixing, and a limit on εB in pp̄ collisions at √s= 1.8 TeV

We present measurements of correlated $b\overline{b}$ cross sections, $\ensuremath{\mu}\ensuremath{-}\ensuremath{\mu}$ correlations, the average ${B}^{0}{\overline{B}}^{0}$ mixing parameter $\overline{\ensuremath{\chi}}$, and a limit on the CP-violating parameter ${\ensuremath{\epsilon}}_{B}.$ For these measurements, we use muon pairs from $b\overline{b}$ double semileptonic decays. The data used in this analysis were taken with the Collider Detector at Fermilab and represent an integrated luminosity of $17.4\ifmmode\pm\else\textpm\fi{}0.6$ pb${}^{\ensuremath{-}1}$. The results concerning $b\overline{b}$ production correlations are compared to predictions of next-to-leading order QCD computations.
