TLDR
In this paper, the value of the quark condensate from quenched QCD simulations on the lattice was determined by using the Gell-Mann-Oakes-Renner (GMOR) formula and comparing the OPE prediction for the Goldstone pole contribution to the pseudoscalar vertex.About:

Meson masses and decay constants from unquenched lattice QCD
TL;DR: In this article, the mass of the nonsinglet light meson and the light vector meson were derived from unquenched lattice QCD at two lattice spacings.
Journal ArticleDOI
Operator product expansion and quark condensate from lattice QCD in coordinate space
TL;DR: In this paper, a lattice QCD determination of the chiral quark condensate based on a new method was presented, where the quark was extracted from the operator product expansion (OPE) of the propagator at short euclidean distances.

Renormalization constants of quark operators for the non-perturbatively improved Wilson action
TL;DR: In this article, an extensive lattice calculation of the renormalization constants of bilinear and four-quark operators for the non-perturbatively (a)-improved Wilson action is presented.
Journal ArticleDOI
Operator product expansion and quark condensate from LQCD in coordinate space
TL;DR: In this article, an exploratory study of the operator product expansion of the quark propagator on the lattice at short distance in coordinate space was performed, which allowed a simple determination of the condensate, Z^MS(2 GeV)=(-265\pm 5\pm 22 MeV)^3.

An Estimate of the chiral condensate from unquenched lattice QCD
TL;DR: Using the parameters in the chiral Lagrangian obtained by MILC from their unquenched lattice QCD calculations with 2 + 1 flavours of sea quarks, the authors estimate chiral condensate.

A general method for non-perturbative renormalization of lattice operators
Guido Martinelli,Guido Martinelli,C. Pittori,Christopher T. Sachrajda,Massimo Testa,Anastassios Vladikas +5 more
TL;DR: In this paper, a non-perturbative method for computing the renormalization constants of generic composite operators is proposed, which is intended to reduce some systematic errors, which are present when one tries to obtain physical predictions from the matrix elements of lattice operators.

Non-perturbative quark mass renormalization in quenched lattice QCD
TL;DR: In this paper, the renormalization factor relating the bare to the group invariant quark masses is accurately calculated in quenched lattice QCD using a recursive finite-size technique.

New Approach to the Renormalization Group
TL;DR: In this paper, a renormalization-group equation for arbitrary momenta is presented, where counterterms are calculated for zero unrenormalized mass and the solutions involve a momentum-dependent effective mass as well as a momentumdependent effective coupling constant.
