On the color structure of Yang-Mills theory with static sources in a periodic box
L. Giusti, A. L. Guerrieri, S. Petrarca +2
We present an exploratory numerical study on the lattice of the color structure of the wave functionals of the SU(3) Yang-Mills theory in the presence of a static pair. I…
Remarks on the Gauge Dependence of the RI/MOM Renormalization Procedure
L. Giusti, S. Petrarca, B. Taglienti +1
The RI/MOM non-perturbative renormalization scheme is studied on the lattice in SU(3) quenched QCD with Wilson fermions. The gauge dependence of some fermion bilinear renormalizati…
Quark and Gluon Propagators in Covariant Gauges
L. Giusti, M. L. Paciello, S. Petrarca +2
We present data for the gluon and quark propagators computed in the standard lattice Landau's gauge and for three values of the covariant gauge-fixing parameter lambda=0,8,16. Our…
On the Definition of Gauge Field Operators in Lattice Gauge-Fixed Theories
L. Giusti, M. L. Paciello, S. Petrarca +2
We address the problem of defining the gauge four-potential on the lattice, in terms of the natural link variables. Different regularized definitions are shown, through non perturb…
Gribov Copies and Smeared Correlation Functions in Lattice QCD
M. L. Paciello, C. Parrinello, S. Petrarca +2
We study the influence of Gribov copies in the Coulomb gauge on the smeared hadronic correlation functions that are involved in the determination of the B meson decay constant. We…
