Proceedings of the YIPQS International Workshop
Ed. by K. Itakura, H. Fujii, K. Fukushima, Y. Hatta, Y. Hidaka and H. Kawamura
This volume contains the proceedings for the YITP International
Symposium ``High Energy Strong Interactions 2010'', held August
913, 2010, at the Yukawa Institute for Theoretical Physics (YITP)
in Kyoto, Japan. This symposium was organized as a part
of a fiveweek workshop entitled ``High Energy Strong Interactions
2010 — Parton Distributions and Dense QCD Matter —'', from
July 26 to August 27, 2010. The proceedings include contributions
of the invited speakers at the symposium, notes of lectures given
at the presymposium school, and information about the workshop,
including a list of participants and the titles of talks given at
the workshop.
Research on highenergy hadron scattering has a long history
starting even before the advent of the fundamental theory,
quantum chromodynamics (QCD). However, importance of the
physics of highenergy scattering in particular from the
viewpoint of QCD is getting more and more increased in
relation to highenergy experiments such as the Relativistic
HeavyIon Collider (RHIC) at BNL, the Hadron Electron Ring
Accelerator (HERA) at DESY, Tevatron at FNAL, and the Large
Hadron Collider (LHC) at CERN. The purpose of this
workshop/symposium was to summarize what we have learned so
far about highenergy QCD from the data obtained from these
experiments.
The topics discussed in the workshop/symposium include the
following:
(1) Structure Functions and Spin Physics:
Polarized and unpolarized parton distributions,
TMD distribution/fragmentation, highertwist effects,
generalized parton distribution, lowx physics and saturation
(2) HeavyIon Collisions:
Hard probes, jet quenching, color glass condensate,
multiparticle correlations, initial conditions and thermalization
mechanisms
(3) NonPerturbative Approaches:
AdS/CFT and holographic QCD applications, phenomenological models,
lattice QCD simulations
During the five weeks, 102 registered participants took part in the
program. There were 42 talks given at the workshop and 32 talks given
at the symposium, as well as 3 lectures given at the presymposium
school. In particular, the highlights from all six experimental
collaborations of LHC, namely ALICE, CMS, ATLAS, LHCb, LHCf, TOTEM,
were reported and discussed during the symposium week, for the first
time in Japan.
