Landau gauge ghost propagator and running coupling inSU(2)lattice gauge theory

Abstract: We study finite (physical) volume and scaling violation effects of the Landau gauge ghost propagator as well as of the running coupling αs(p) in the SU (2) lattice gauge theory. We consider lattices with physical linear sizes between aL ≃ 3 and aL ≃ 7 fm and values of lattice spacing between a = 0.2 and a = 0.07 fm. To fix the gauge we apply an efficient gauge fixing method aimed at finding extrema as close as possible to the global maximum of the gauge functional. We find finite volume effects to be small for… Show more

“…Most of the non-perturbative approaches that have been developed so far rely on numerical calculations in the Euclidean space, where synergic studies by lattice simulations [2][3][4][5][6][7][8][9][10], Schwinger-Dyson equations [11][12][13][14][15][16][17][18][19][20][21] and variational methods [22][23][24][25][26][27][28][29][30][31][32] have drawn a clear picture for the propagators of QCD deep in the IR.…”

“…Apart from completing the set of renormalization constants and the RGE of the theory, which is important in itself, the gauge boson and ghost propagator anomalous dimensions serve another purpose. These quantities are essential ingredients in comparing the momentum dependence of the corresponding propagators derived in non-perturbative calculations on the lattice, with perturbative results (see e. g. [11][12][13][14][15][16][17][18]). This paper is structured as follows: First, we will give the notation and definitions for the model and the computed RG functions We will also repeat how the special case of QCD plus Majorana gluinos in the adjoint representation of the gauge group can be derived from our more general results.…”
