Lecturers
- QCD at non-zero temperature : status and prospects
Dr. Peter Petreczky
Brookhaven, USA
Lecture Abstract:
I am going to review several topics in lattice QCD at non-zero temperature.
I will discuss deconfining and chiral aspects of the finite temperature transition in
QCD, and the role of universality (scaling) in describing the chiral transition and
in the determination of the corresponding transition temperature. I will also
mention the effective restoration of U_A(1) symmetry at high temperatures.
The deconfining aspects of the transition will be discussed in terms of fluctuations
of conserved charges, that are sensitive to the underlying degrees of freedom, and onset
of color screening. The present status of the calculations of equation of state will
be reviewed. The results of the lattice calculations will be compared to the calculations
obtained using weak coupling techniques as well as with the predictions of
Hadron Resonance Gas (HRG) model. The comparison with the weak coupling results is important
for establishing the temperature range where quark gluon plasma can be considered as
weakly coupled, while comparison with HRG is important to test the validity of effective
models. Finally, I will review progress made in calculating meson correlation functions and
extracting transport coefficients. In particular, I will address the question of melting of
quarkonium states in quark gluon plasma.

- Clusters in Nuclear Matter and the Equation of State for Astrophysical
Applications
Dr. Stephan Typel
GSI Helmholtzzentrum fur Schwerionenforschung, Germany
Lecture Abstract:
The equation of state (EoS) of nuclear matter is an essential ingredient
in the description of astrophysical phenomena like neutron stars and
core-collapse supernovae. It has to be known in a wide range of
densities, temperatures and neutron-to-proton asymmetries. Constraints
for the EoS can be obtained from a variety of fields: properties of
nuclei, nucleon-nucleon scattering, heavy-ion collisions and astronomical observations. The thermodynamical properties of matter are strongly affected
by correlations, in particular the appearance of inhomogeneities and
the formation of clusters that also modify the chemical composition
of the system. Vice versa, the properties of nuclei, e.g. their binding
energies, change in a dense medium. In the lectures, these features will
be discussed in the context of an extended relativistic density functional approach in comparison to other models.
- Cosmic Rays and Hadronic Physics
Prof. Dr. Paolo Lipari
INFN and Dipartimento di Fisica University of Roma, Italy
Lecture Abstract:
These lectures want to give an introduction to the
present status of Astroparticle Physics, giving special emphasis
to a discussion of the importance of the description
of hadronic interactions in the interpretation of the
observations of cosmic rays at the highest energy.
The lectures will include a summary of recent
results in cosmic rays, gamma astronomy and neutrino astronomy,
and a brief discussion of the study of the
nature of Dark Matter from observations of cosmic ray fluxes.
The study of the cosmic rays at the highest energies requires
the modeling of hadronic interactions up to a c.m. energy
of 400 TeV. Measurements at LHC can help in the
extrapolation to these energies.
