Heavy quark production provides a sensitive window for the study of the gluon structure of nucleons and its modification in nuclei. It also provides a very important means of studying the hot‐dense conditions created in high‐energy collisions of heavy nuclei and a critical probe to look for de‐confinement in this hot‐dense matter. I will review, from an experimental point of view, the physics issues as seen in current experimental results for charm production and point out the remaining puzzles. |
