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…
The Infrared Behaviour of the Pure Yang-Mills Green Functions
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We review the infrared properties of the pure Yang-Mills correlators and discuss recent results concerning the two classes of low-momentum solutions for them reported in literature…
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…
The low-momentum ghost dressing function and the gluon mass
José Rodríguez-Quintero
We study both regular (the zero-momentum ghost dressing function not diverging), also named decoupling, and critical (diverging), also named scaling, Yang-Mills propagators solutio…
The low-momentum ghost dressing function and the gluon mass
Ph. Boucaud, M. E. Gómez, J. P. Leroy +4
We study the low-momentum ghost propagator Dyson-Schwinger equation (DSE) in Landau gauge, assuming for the truncation a constant ghost-gluon vertex, as it is extensively done, and…
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…
