Findings

New measurements agree with theoretical predictions.

Confirmed the absence of previously observed anomalies.

Clarified the experimental situation regarding b-quark production.

Abstract

The measurement of heavy quark cross-sections provides important tests of the QCD theory. This paper reviews recent measurements of single b-quark and correlated b-quark cross-sections at CDF. Two new measurements of the single b-quark production at CDF agree with the first result from CDF Run II. This clarifies the experimental situation and confirms the recent agreement of theoretical prediction with data. A new measurement of the correlated $b\bar{b}$ cross-section with dimuon events at CDF is presented. It agrees with theory and it does not confirm the anomalously large $b\bar{b}$ cross-section seen in Run I by CDF and D${\not {\rm O}}$ in dimuon events.
