Proceedings of the YITP International Workshop/Symposium
Edited by T. Kunihiro, K. Fukushima, T. Hirano, H. Iida,

This volume contains the proceedings of the four-day international symposium,
"Fundamental Problems in Hot and/or Dense QCD"
held at the Yukawa Institute for Theoretical Physics, Kyoto University,
from March 3 to March 6, 2008,
as well as the records of the long-term international workshop,
"New Frontiers in QCD 2008 — Fundamental
Problems in Hot and/or Dense Matter —",
held from January 28 to March 21, 2008.
The recent precise experimental data
from RHIC (Relativistic Heavy-Ion Collider)
at Brookhaven National Laboratory, USA
are giving us a much deeper understanding
of QCD matter (Quark-Gluon-Plasma),
and new theoretical techniques have been developed.
Also, the new aspects of high-density quark matters are emerging.
Based on these recent progresses,
we discussed the following topics in this conference.
(i)   Early thermalization of Quark Gluon Plasma
(ii)   Dissipations and the success in fluid description of QGP
(iii)   Properties of strongly-correlated QCD matter created at RHIC
(iv)   Initial condition in relativistic heavy ion collisions
in terms of Color Glass Condensate
(v)   Ground state of high-density quark matters
under the electric- and color- neutrality
(vi)   QCD dynamics including quark-pair condensate
(vii)  Nonperturbative techniques such as
lattice QCD simulations or gauge/gravity
In the symposium,
active researchers at the forefront of each field
presented up-to-date research outcomes,
and vigorous discussions were held.
This volume, which contains the oral presentations in the symposium,
gives the very present status of our understanding.
We believe that these conference minutes contribute to
further development in the fields
and would be very useful for non-experts or students
who have interest and want to look over the recent progresses
in these research fields.
