Modified instanton profile effects from lattice Green functions
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<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 mod...

| Sumario: | 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<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. |
