The aim of these lectures is to provide students with an introduction to some of the core concepts and methods of QCD that are relevant in an LHC context.
With the energy scales opened up by Rhic and Lhc the age of high-pT physics is upon us. This has created new opportunities and novel mysteries, both of which will be explored in this thesis. The possi...
Bosonic string behavior in UV filtered QCD
Bosonic Strings Finite temperature QCD Flux tubes
2011/1/13
The quark–antiquark potential and the gluonic action-density are calculated on sets of smeared gauge-field configurations at finite temperature just below the deconfinement temperature.
QCD, monopoles on the Lattice and gauge invariance
QCD Lattice Monopoles Color confinement
2011/1/13
The number and the location of the monopoles observed on the lattice in QCD configurations happens to depend strongly on the choice of the gauge used to expose them, in contrast to the physical expect...
Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
nonperturbative QCD, QCD sum rules quark–hadron duality continuum threshold charmed or beauty meson heavy-quark mass
2011/1/7
We present a sum-rule extraction of decay constants of heavy mesons from the two-point correlator of heavy-light pseudoscalar currents.
Charmonium-nucleon interaction from lattice QCD with a relativistic heavy quark action
Charmonium-nucleon interaction lattice QCD relativistic heavy quark action
2011/1/13
Detailed information of the low-energy interaction between the charmonia (hc and J=y) and the
nucleon is indispensable for exploring the formation of charmonium bound to nuclei. In order
to investig...
Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
Comparison mass preconditioned HMC DD-HMC algorithm two-flavour QCD
2011/1/13
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic
quark masses and l...

Continuum Limit Physics 2+1 Flavor Domain Wall QCD
2011/1/13
We present physical results obtained from simulations using 2+1 flavors of domain wall quarks
and the Iwasaki gauge action at two values of the lattice spacing a, (a−1= 1.73 (3)GeV and
a−...
Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
Possible splitting of deconfinement chiral transitions strong magnetic fields
2011/1/14
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...

2011/1/14
We present a sum-rule extraction of the decay constants of heavy-lightmesons from the two-point
correlator of pseudoscalar currents [1]. To this end, we compare the perturbative expansions for the co...

2011/1/14
We present a sum-rule extraction of decay constants of heavy mesons from the two-point correlator of heavy-light pseudoscalar currents. Our primary concern is to control the uncertainties of the decay...
Electromagnetically superconducting phase of QCD vacuum induced by strong magnetic field
Quantum Chromodynamics Strong Magnetic Fields Superconductivity Rho Condensation
2011/1/14
In this talk we discuss our recent suggestion that the QCD vacuum in a sufficiently strong magnetic field (stronger than 1016 Tesla) may undergo a spontaneous transition to an electromagnetically supe...
Recent developments on the determination of the spin-1/2 spectrum of the nucleon in full QCD
are presented. Our focus is on the PACS-CS 2+1 flavor configurationsmade available through the
ILDG.

Curvature QCD phase transition line finite volume
2011/1/14
The curvature which characterizes the QCD phase transition at finite temperature and small
values of the chemical potential is accessible to lattice simulations. The results for this quantity which h...
Phase diagram of dense quark matter in QCD-like theories
Confinement Chiral Symmetry Breaking QCD Spontaneous Symmetry Breaking
2011/1/7
I report the results of a series of works on the phase diagram of theories with a different number of colors and/or quarks in a different representation than in QCD. Similarities as well as difference...
