From the Quark Discovery to Heavy-Ion Collisions I
- Jean-Philippe Lansberg
09:10 - 10:40
Room: JungSeok Memorial Library In these lectures, I first briefly review the emergence of Quantum Chromodynamics (QCD) as the theory of the strong interaction. I introduce concepts such as colour, Bjorken scaling, asymptotic freedom and confinement. This serves as a natural motivation for the study of heavy-ion collisions as a means a study the phenomenon of deconfinement at high nuclear densities and temperatures and the creation of a new state of matter such as a quark-gluon plasma (QGP). I also introduce and discuss the basic tools to tune the conditions of such collisions and the most current probes of a QGP at RHIC and the LHC.

Soft and Hard Physics of Quark-Gluon Plasma I
- Sangyong Jeon
11:10 - 12:40
Room: JungSeok Memorial Library In the past two decades, creation and investigation of quark-gluon plasma (QGP) have been {\em the} most important goal of the high-energy nuclear physics community. With two powerful heavy ion colliders in operation - RHIC and the LHC, we have learned much about this fascinating new state of matter which existed in bulk only about a micro-second after the big-bang. QGP is hottest matter ever seen - its temperature exceeds at least two trillion kelvin so that the hadrons must dissolve. QCD is densest matter ever seen - a cubic centimeter of QGP weighs about 10 times the whole population of earth. Yet, it is not hot enough and dense enough that perturbative QCD can be applied. Furthermore, QGP we create in relativistic heavy ion collisions is not static. It evolves into the ordinary hadronic matter within a few fm/c where as the usual theoretical tools such as the Feynman diagrams are not really formulated to deal with evolving systems. Yet, theorists have met the challenge of devising ways to study this system with confidence and learned much about the properties of QGP and how it is created in relativistic heavy ion collisions. In this lecture, I will emphasize the need to understand the different time and length scales that makes it possible for us to use certain approximations and also emphasize the need to understand {\em both} the soft and the hard physics of the relativistic heavy ion collisions and interactions between them. In particular, the theory and practice of QGP hydrodynamics and the jets and photons that propagate through QGP will be discussed. Due to the time restriction, this lecture will be more about {\em qualitative} understanding rather than the details of calculations.

Collider Experiments: from accelerators to detectors I
- Jochen Klein
16:00 - 17:30
Room: JungSeok Memorial Library Many current experiments in particle and nuclear physics are and will be carried out at particle colliders. We will first discuss the basic concepts and the technologies used in a modern accelerator complex, starting from a particle source, through the injector chain, to the accelerator used for experiments. Where relevant the Large Hadron Collider will serve as an example. Next, we will discuss the ideas and concepts in typical experiments at hadron colliders. We will describe some detector types in more detail, i.e. explain the detector physics relevant for the signal generation, the front-end electronics used for the read-out, and the basic algorithms used for reconstruction. LHC experiments and, in particular, ALICE detectors will again serve as an example where useful.

Effective QCD-like models at finite temperature and density
- Seung-il Nam
11:20 - 12:40
Room: JungSeok Memorial Library In this talk, I briefly introduce a couple of QCD-like effective models, such as the Polyakov-loop Nambu--Jona-Lasinio model (pNJL) and the caloron-modified instanton-liquid model (mLIM) for the hot and dense QCD matter. The talk will be given starting from vacuum properties, then gradually moving to the extreme conditions of QCD, via intuitive and pedagogical ways for beginners. I also show important physical quantities calculated by the models to understand the various phenomena in the hot and dense QCD.

Saturation and scaling properties in high energy scattering: from deep inelastic scattering to heavy ion collisions.
- Michal Praszałowicz
14:00 - 15:30
Room: JungSeok Memorial Library By scaling we understand a property of certain physical observables that in principle should depend on two kinematical variables but in reality depend only on a particular combination of them. A prominent example is so called Bjorken scaling that paved the road to the present understanding of the proton structure. After a a short reminder of the Bjorken scaling we shall introduce geometrical scaling (GS). GS follows from the fact that there exists an intermediate momentum scale, called saturation scale. We shall give physical interpretation of GS. By inspecting different pieces of data we shall demonstrate the existence
