Has HERA reached a new QCD regime?
These notes are a summary of our efforts to answer the question in the title.
Our answer is in the affirmative as: (i) HERA data indicate a large value of
the gluon structure function; (ii) no contradictions with the asymptotic
predictions of high density QCD have been observed; and (iii) the numerical
estimates of our model give a natural description of the size of deviation from
the routine DGLAP explanation. We discuss the alternative approaches and
possible new experiments.Comment: 29 pages, 37 figures in eps file
Higher twists and maxima for DIS on nuclei in high density QCD region
We show that the ratio of different structure functions have a maximum which
depends on and . We argue that these maxima are proportional to the
saturation scale. The analysis of leading and higher twist contributions for
different observables is given with the aim of determining the kinematic region
where high parton density effects could be seen experimentally.Comment: 16 pages of Latex file,8 figures in eps file
Theoretical Overview Quark Matter '04
The much wider transverse-momentum range accessible in heavy-ion collisions
at RHIC and at the LHC allows us to disentangle the dynamics of partonic
equilibration from the dynamics of delayed hadronization. This provides a novel
tool for testing the equilibration mechanisms underlying QCD thermodynamics.
Here, I argue, on the basis of simple formation-time arguments, why this is so,
and I review recent theoretical developments in this context.Comment: 12 pages, Latex, 3 eps figures, invited introductory talk at Quark

Cold nuclear effects on heavy flavours (a review)
Before wondering about the quark-gluon plasma (QGP), one has to take into
account various cold (normal) nuclear matter effects, that can be probed
through p+A like collisions. This article aims at reviewing the current results
(and understanding) of these effects on heavy quarks and quarkonia production.Comment: 8 pages, 6x2 figures, SQM08 proceedings, version accepted by

SQM 2006: Theory Summary and Perspectives
In this write-up of my SQM 2006 Theory Summary talk I focus on a selection of
key contributions which I consider to have a large impact on the current status
of the field of strangeness physics or which may have the potential to
significantly advance strangeness -- or in general flavor physics -- in the
near future.Comment: 16 pages, 4 figures, SQM 2006 proceedings. Revised version containing
