Query: Open questions in quarkonium and electromagnetic probes   In my ("not a summary") talk at the Hard Probes 2006 conference, I gave "a
personal and surely biased view on only a few of the many open questions on
quarkonium and electromagnetic probes". Some of the points reported in that
talk are exposed in this paper, having in mind the most important of all the
open questions: do we have, today, from experimental data on electromagnetic
probes and quarkonium production, convincing evidence that shows, beyond
reasonable doubt, the existence of "new physics" in high-energy heavy-ion
collisions?
