Ghost-gluon running coupling, power corrections and the determination of
Ph. Boucaud, F. De Soto, J. P. Leroy +4
We compute a formula including OPE power corrections to describe the running of a QCD coupling non-perturbatively defined through the ghost and gluon dressing functions. This turns…
On the IR behaviour of the Landau-gauge ghost propagator
Ph. Boucaud, J. P. Leroy, A. Le Yaouanc +3
We examine analytically the ghost propagator Dyson-Schwinger Equation (DSE) in the deep IR regime and prove that a finite ghost dressing function at vanishing momentum is an altern…
IR finiteness of the ghost dressing function from numerical resolution of the ghost SD equation
Ph. Boucaud, J-P. Leroy, A. Le Yaouanc +3
We solve numerically the Schwinger-Dyson (SD hereafter) ghost equation in the Landau gauge for a given gluon propagator finite at k=0 (alpha_gluon=1) and with the usual assumption…
