Contribution

It provides a comprehensive comparison of heavy flavour production data with theoretical QCD predictions across multiple collider types.

Findings

Measurements generally agree with QCD predictions within uncertainties.

Discrepancies highlight areas for theoretical and experimental improvement.

The analysis identifies specific issues in current models and measurements.

Abstract

The production of charm and beauty quarks in $\gamma \gamma$ collisions at LEP, $ep$ collisions at HERA and $p \bar{p}$ collisions at the Tevatron is discussed. The comparison with predictions of next-to-leading-order QCD and the issues it raises are detailed. In particular, the strengths and weaknesses of the measurements and predictions are discussed.
