TL;DR

This paper reports measurements of correlated $b$ quark production cross sections at Fermilab, comparing experimental results with QCD predictions, using data from the 1992-93 collider run.

Contribution

First measurement of correlated $b$ quark cross sections as functions of momentum and azimuthal separation at Fermilab.

Findings

Measured cross sections as functions of $b$ quark momentum and azimuthal separation.

Results are compared with Quantum Chromodynamics (QCD) predictions.

Data collected during the 1992-93 collider run at Fermilab.

Abstract

Using data collected during the 1992-93 collider run at Fermilab, CDF has made measurements of correlated $b$ quark cross section where one $b$ is detected via a muon from semileptonic decay and the second $b$ is detected with secondary vertex techniques. We report on measurements of the cross section as a function of the momentum of the second $b$ and as a function of the azimuthal separation of the two $b$ quarks, for transverse momentum of the initial $b$ quark greater than 15 GeV. Results are compared to QCD predictions.
