Modified instanton profile effects from lattice Green functions

High Energy Physics - Phenomenology 2016-08-16 v2

Abstract

We trace here instantons through the analysis of pure Yang-Mills gluon Green functions in the Landau gauge for a window of IR momenta (0.4 GeV <k<0.9< k < 0.9 GeV). We present lattice results that can be fitted only after substituting the BPST profile in the Instanton liquid model (ILM) by one based on the Diakonov and Petrov variational methods. This also leads us to gain information on the parameters of ILM.
