Program with talk slides
Monday, August 3
Philippe De Forcrand(ETH Zurich and CERN)
Time: 09:10-09:50
Title: QCD at finite temperature and density from lattice simulations
Donald Keith Sinclair(Argonne National Laboratory)
Time: 09:50-10:20
Title: Thermodynamics of QCD with colour-sextet quarks
Abstract:
We are studying the thermodynamics of lattice QCD with 2 flavours of colour-sextet quarks. This theory is of interest because of the proximity of an infrared fixed point. Such theories are of interest to people studying extensions of the standard model which have a strongly interacting Higgs sector [such as quasi-conformal (walking) Technicolor].

Masanobu Yahiro(Kyushu University)
Time: 10:20-10:50
Title: Imaginary chemical potential and determination of QCD phase diagram
Abstract:
Recently we have analyzed the imaginary chemical potential region by using the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model. This work has already been published in five papers, Phys. Rev. D77, 051901 (2008), Phys. Rev. D78, 036001 (2008), Phys. Rev. D78 076007 (2008), Phys. Rev. D 79, 076008 (2009), Phys. Rev. D 79, 096001 (2009). I will give a review talk of these works. QCD with the imaginary chemical potential has a symmetry called the extended Z_3 symmetry. This symmetry guarantees that the thermodynamical potential has the Roberge-Weiss periodicity. The PNJL model is only a model that has the extended Z_3 symmetry and the chiral symmetry. As a result of this property, the PNJL model can reproduce lattice QCD data in the imaginary chemical potential region. The parameters of the PNJL model are fitted to the data. After this imaginary chemical potential matching, we predict the QCD phase diagram in the real chemical potential region. The imaginary chemical potential dependence of pion and sigma meson masses is also presented.

Title: Finite temperature/density simulation of two-color QCD
Soonwook Hwang(KISTI)
Time: 14:30-15:00
Title: Large scale deployment of two-color QCD on the FKPPL VO using Ganga
Abstract:< /br> A large-scale deployment of two-color QCD simulations on the Grid infrastructure called the FKPPL (France-Korea Particle Physics Laborotory) VO (Virtual Organization) has recently been carried out. In this talk, we introduce the FKPPL VO built across the two computing centers in Korea and France to provide researchers in both countries with computing and storage resources. We also talk about our preliminany experience in the adoption of Ganga, a job submission and management tool developed by CERN, to effectively maintain QCD simulation jobs on the Grid on such a large scale. Issues relating to executing long-running QCD jobs on the Grid such as grid proxy certificates expiration will be addressed as well.
Francesco Di Renzo(University of Parma & INFN)
Time: 15:00-15:30
Title: The Dirac operator spectrum from a perturbative approach
Abstract:
Through the Bank-Casher relation the chiral condensate is connected to the quark modes density at the low end of the spectrum of the Dirac operator.
By computing the spectrum by means of Numerical Stochastic Perturbation Theory, we aim at throwing some light on the widely accepted picture for the mechanism which is behind the Bank-Casher relation.
The spontaneous breaking of chiral symmetry implies that a small quark mass has a deep impact on the QCD vacuum. With this respect the Bank-Casher relation is natural: for the previous picture to hold there should be an accumulation of eigenvalues in the low end of the spectrum. This can be in turn ascribed to the usual mechanism of repulsion among eigenvalues which is typical of quantum interaction.
First results appear to confirm that NSPT can indeed enable to inspect the eigenvalues reshuffling due to quantum repulsion.
Barak Bringoltz(University of Washington)
Time: 15:50-16:10
Title: Solving two-dimensional large-N QCD at nonzero baryon density and arbitrary quark mass
Abstract:
We solve two-dimensional large-N QCD in the presence of a nonzero baryon number B, and for arbitrary quark mass m and volume L. We fully treat the dynamics of the gluonic zero modes and check how this affects results from previous studies of the B=0 and B=1 systems. For a finite density of baryons, and for any m>0, we find that the ground state contains a baryon crystal with expectation values for <psi-bar gamma_mu psi> that have a helix-like spatial structure. We study how these evolve with B and see that the volume integral of <psi-bar psi> strongly changes with the baryon density. We compare this emerging crystal structure with the sine-Gordon crystal, which is expected to be a good approximation for light quarks, and find that it is a very good approximation for surprisingly heavy quarks. We also calculate the energy and quark chemical potential mu as a function of the density and this allows us to translate our findings to the grand-canonical ensemble. The resulting phase structure along the mu-axis contains a phase transition that occurs at a value of mu equal to the baryon mass divided in N, and that separates a mu-independent phase with intact translation symmetry from a mu-dependent phase with spontaneously broken translation symmetry. Finally, our calculations confirm the presence of a partial large-N Eguchi-Kawai volume independence, as described in arXiv:0811.4141, that arises only if one treats the gluonic zero modes correctly.
Marco Panero(ETH Zurich)
Time: 16:10-16:40
Title: Hot and colorful - Thermodynamics of the deconfined gluon plasma in the large-N limit
Abstract:
The main thermodynamic observables of the deconfined gluon plasma in SU(N) gauge theories are studied numerically on the lattice. The results obtained in theories with N=3, 4, 5, 6 and 8 colors show strong qualitative and quantitative similarities. The theoretical implications of these findings and their potential relevance for phenomenological descriptions of the QCD plasma based on the AdS/CFT correspondence are briefly discussed.
Takuya Saito(Kochi University)
Time: 16:40-17:10
Title: Gluon propagators in the quark-gluon plasma
Abstract:
We report lattice results of gluon propagators, screening electric
and magnetic masses above Tc in the SU(3) gauge theory.
Moreover, we discuss properties of infrared gluons in terms of
center vortex mechanism in the SU(2) lattice simulations.
Tuesday, August 4
Sangyong Jeon(McGill University)
Time: 09:00-09:30
Title: Jets and Photons in evolving QGP
Abstract:
The temperature reached in relativistic heavy ion collisions is high enough for quark-gluon plasma formation. Hard probes such as jets and high energy photons can be used to study the properties of the QGP.
In this talk, I will present our calculation of jet and photon spectra based on high temperature QCD, fully taking into account the hydrodynamic evolution of the QGP.

Xiaohong Wu(East China University of Science and Technology)
Time: 11:50-12:20
Title: Holographic QCD beyond the leading order
Abstract:
We consider a holographic QCD model for light mesons beyond the leading
order in the context of 5-dim gauged linear sigma model on the interval
in the AdS$_5$ space. We include two dimension-6 operators in addition
to the canonical bulk kinetic terms, and study chiral dynamics of $\pi$,
$\rho$, $a_1$ and some of their KK modes. As novel features of dim-6
operators, we get non-vanishing Br$(a_1 \to \pi \gamma)$, the
electromagnetic form factor and the charge radius of a charged pion,
which improve the leading order results significantly and agree well
with the experimental results.
Sang-Jin Sin(Hanyang University)
Time: 14:00-14:30

Yoshiyuki Nakagawa(Hiroshima University)
Time: 14:30-15:00
Title: Lattice study of entanglement entropy in SU(3) pure Yang-Mills theory
Takashi Sano(University of Tokyo)
Time: 15:00-15:30
Title: A chiral random matrix model for 2+1 flavor QCD at finite temperature and density(temporal title)
Abstract:
The conventional chiral random matrix models are known to predict a second-order phase transition at finite temperature irrespective of the number of flavors. Here we propose a random matrix model which properly contains the UA(1) breaking term and as a result predicts a first-order phase transition for the three-flavor case. This is the first chiral random matrix model which allows us to investigate the effects of the strange quark degree on the QCD phase diagram, especially on the QCD critical point, at finite temperature and density. Taking the scalar quark condensates as the order parameters, we explore the phase structure of this model in the space of the temperature, the quark number chemical potential and the quark masses.
