Finite-size scaling of the quark condensate in quenched lattice QCD
نویسندگان
چکیده
We confront the finite volume and small quark mass behaviour of the scalar condensate, determined numerically in quenched lattice QCD using Neuberger fermions, with predictions of quenched chiral perturbation theory. We find that quenched chiral perturbation theory describes the numerical data well, allowing us to extract the infinite volume, chiral limit scalar condensate, up to a multiplicative renormalization constant.

Quenched lattice QCD at finite isospin density and related theories
We study quenched QCD at finite chemical potential, μI , for the third component of isospin and quenched two-colour QCD at finite chemical potential, μ, for quark number. In contrast to the quenched approximation to QCD at finite quark-number chemical potential, the quenched approximations to these theories behave similarly to the full theories. The reason is that these theories have real posit...
متن کاملMixed Quark-Gluon condensate at finite temperature and density in the global color symmetry model
The mixed quark-gluon condensate is another chiral order parameter in QCD, which plays an important role in the application of QCD sum rules. In this letter, we study the properties of quark-gluon mixed condensate at finite temperature and quark chemical potential in the framework of global color symmetry model. Using an infrareddominant model gluon two-point function, we find that the behavior...
متن کاملPreliminary results from a simulation of quenched QCD with overlap fermions on a large lattice
We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at β = 6 on an 18 3 × 64 lattice. We calculate quark propagators for a single source point and quark mass ranging from amq = 0.03 to 0.75. We present here preliminary results based on the propagators for 60 gauge field configurations. 1. Introduction The closely related domain wall [1,2] and overlap [...
متن کاملOn the renormalized scalar density in quenched QCD
We present a non-perturbative determination of the renormalization factor Z S of the scalar density in quenched QCD with overlap fermions. Results are obtained at four values of the lattice spacing. By combining Z S with results for the low-energy constant Σ we are able to compute the renormalization group invariant scalar condensate Σ in the continuum limit with a total accuracy of 7%, excludi...
متن کاملPartially Quenched Chiral Condensates from the Replica Method
A large-Nf expansion is used to compute the partially quenched chiral condensate of QCD in the microscopic finite-volume scaling region. NBI-HE-00-01 hep-lat/0001002 While the replica method has found widespread use in condensed matter physics as a means of generating quenched averages, it has only rarely been applied in particle-physics contexts. Analytical approaches to quenching – so often u...
