Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD exact chiral symmetry
2011/1/13
Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...
Exploring quark transverse momentum distributions with lattice QCD
Exploring quark transverse momentum distributions lattice QCD
2011/1/13
We discuss in detail a method to study transverse momentum dependent parton distribution
functions (TMDs) using lattice QCD. To develop the formalism and to obtain rst numerical results,we directly ...
OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
OPE Heavy-Quark Mass Heavy-Meson Decay Constants from QCD Sum Rules
2011/1/7
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...
Wave Functions of the Proton Ground State in the Presence of a Uniform Background Magnetic Field in Lattice QCD
Wave Functions of the Proton Ground State Uniform Background Magnetic Field
2011/1/13
We calculate the probability distributions of quarks in the ground state of the proton, and how
they are a ected in the presence of a constant background magnetic eld. We focus on wave functions in ...

We present the results of the recent high precision lattice calculation of the average up/down,
strange and charm quarkmasses performed by ETMC with Nf =2 twisted massWilson fermions.
The analysis i...
Non-linear QCD dynamics and exclusive production
Non-linear QCD dynamics exclusive production
2011/1/5
In this contribution we analyse the cross sections for the exclusive vector meson production as
well as the deeply virtual Compton scattering (DVCS) relying on the color dipole approach and
consider...
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.
Flavor structure of the baryon-baryon interaction from lattice QCD

2011/1/13
We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...
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...
Evidence for a First Order, Finite Temperature Phase Transition in 8 Flavor QCD
Evidence First Order Finite Temperature Phase Transition
2011/1/13
As part of our ongoing investigations of QCD with many flavors of quarks, here we report on
studies of the finite temperature phase transition for eight-flavor QCD with the DBW2 gauge
action and na&...
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...
Systematic errors in extracting nucleon properties from lattice QCD
Systematic errors extracting nucleon properties lattice QCD
2011/1/13
Form factors of the nucleon have been extracted from experiment with high precision. However,
lattice calculations have failed so far to reproduce the observed dependence of form factors on
the mome...

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
