mu-Squared Dependent Deviation of the Non Perturbative ZA,MOM from the True Axial Renormalisation Constant, Implied by Ward Identity
Ph. Boucaud, J. -P. Leroy, A. Le Yaouanc +3
It is recalled why, as already stated in a previous paper, there seems to be an inconsistency in identifying the non perturbative ZA,MOM as the renormalisation of the axial current…
Vacuum expectation value of A^2 from LQCD
O. Pène, B. Blossier, Ph. Boucaud +10
We argue from LQCD that there is a non vanishing v.e.v of in QCD in the Landau gauge. We use operator product expansion to provide a clear definition of a…
Quark pseudoscalar vertex and quark mass function with clover fermions : spontaneous symmetry breaking, OPE, symmetry restoration at small volume
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We study the quark mass function on hypercubic lattices, in a large range of physical volumes and cutoffs. To avoid the very large Wilson term artefact, we exploit the relation bet…
Short comment about the lattice gluon propagator at vanishing momentum
Ph. Boucaud, Th. Brüntjen, J. P. Leroy +6
We argue that all evidences point towards a finite non-vanishing zero momentum renormalised lattice gluon propagator in the infinite volume limit. We argue that different simulatio…
Non-Perturbative Approach to the Landau Gauge Gluodynamics
A. Y. Lokhov, Ph. Boucaud, J. P. Leroy +5
We discuss a non-perturbative lattice calculation of the ghost and gluon propagators in the pure Yang-Mills theory in Landau gauge. The ultraviolet behaviour is checked up to NNNLO…
Non-perturbative Power Corrections to Ghost and Gluon Propagators
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +5
We study the dominant non-perturbative power corrections to the ghost and gluon propagators in Landau gauge pure Yang-Mills theory using OPE and lattice simulations. The leading or…
