Non-perturbative improvement of lattice QCD at large momenta
نویسندگان
چکیده
We propose a method to improve lattice operators composed of Wilson fermions which allows the removal of all corrections of O(a), including those proportional to the quark mass. It requires off-shell improvement of quark fields and composite operators, which is achieved by studying the behaviour of quark and gluon correlation functions at large momenta.

Non-Perturbative Improvement of the Anisotropic Wilson QCD Action
The simulation of charm or bottom quarks on (a sequence of) lattices with amq≪1 is currently not affordable, even in the quenched approximation. Since standard lattice actions break down when amq>1, one must design special actions to study heavy quarks. Currently two approaches are widely used: (i) Non-relativistic lattice QCD (NRQCD) [1], and (ii) the “heavy relativistic” or “Fermilab” approac...
متن کاملGluons, Quarks, and the Transition from Nonperturbative to Perturbative Qcd
Lattice-based investigations of two fundamental QCD quantities are described, namely the gluon and quark propagators in Landau gauge. We have studied the Landau gauge gluon propagator using a variety of lattices with spacings from a = 0.17 to 0.41 fm to explore finite volume and discretization effects. We also introduce the general method of “tree-level correction” to minimize the effect of lat...
متن کاملNon–perturbative computation of gluon mini–jet production in nuclear collisions at very high energies
At very high energies, in the infinite momentum frame and in light cone gauge, a hard scale proportional to the high parton density arises in QCD. In an effective theory of QCD at small x, this scale is of order αSμ, where μ is simply related to the gluon density at higher rapidities. The ab initio real time evolution of small x modes in a nuclear collision can be described consistently in the ...
متن کاملO(a) Improved Lattice Qcd *
We review the O(a) improvement of lattice QCD with special emphasis on the motivation for performing the improvement programme non-perturbatively and the general concepts of on-shell improvement. The present status of the calculations of various improvement coefficients (perturbative and non-perturbative) is reviewed, as well as the computation of the isospin current normalization constants ZA ...

The thermodynamics of the SU(3) gauge theory has been analyzed with tree level and tadpole improved Symanzik actions. A comparison with the continuum extrapolated results for the standard Wilson action shows that improved actions lead to a drastic reduction of finite cutoff effects already on lattices with temporal extent Nτ = 4. Results for the pressure, the critical temperature, surface tensi...
