Unveiling the flux tube structure in full QCD

Abstract We present lattice Monte Carlo results on the chromoelectric field created by a static quark–antiquark pair in the vacuum of QCD with 2+1 dynamical staggered fermions at physical masses. After isolating the nonperturbative, confining part of the field, we characterize its spatial profile fo...

Description
Summary:Abstract We present lattice Monte Carlo results on the chromoelectric field created by a static quark–antiquark pair in the vacuum of QCD with 2+1 dynamical staggered fermions at physical masses. After isolating the nonperturbative, confining part of the field, we characterize its spatial profile for several values of the physical distances between the sources, ranging from about 0.5 fm up to the onset of string breaking. Moreover, we compare our results with a model of QCD vacuum as disordered chromomagnetic condensate.
