Identification of gaps in current QCD understanding

Abstract

Substantial advances in our understanding of several aspects of QCD have been achieved in the recent past using heavy quarks as a tool. However, many open questions still remain. These successes and puzzles are highlighted by the latest measurements of heavy quark production at the Tevatron, HERA and fixed target experiments, which will be reviewed here. Results in both open heavy flavor and heavy quarkonium production as well as evidence for new particles containing heavy quarks will be presented. The impact of these measurements on gaps in our understanding of QCD and how we hope to close these gaps in the future will be outlined.
