Modified instanton profile effects from lattice Green functions. Physical Review D, 70(11). DOI: https://doi.org/10.1103/physrevd.70.1145032470-0010http://hdl.handle.net/10272/18545We 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<k<0:9 GeV). We present lattice results that can be fitted only after substituting the Belavin-Polyakov-Shvarts-Tyupkin 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 the ILM.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Modified instantonLattice green functionsjournal articleopen access
