It shows a dramatic proptop4 law which can be understood within an instanton liquid model. In this framework the prefactor gives a direct measure of the instanton density in thermalised configurations. A preliminary result for this density is 5.27(4) fm¿4.application/pdfenIOP PublishingLattice Gauge field theoriesConfinementSolitons monopoles and instantonsLattice QCDThe strong coupling constant at small momentum as an instanton detectorjournal articleopen access
