Flux tubes in Nf=2+1 QCD with external magnetic fields
Abstract
We study the behavior of the confining flux tube in Nf=2+1 QCD at the physical point, discretized with the stout smearing improved staggered quark action and the tree level Symanzik gauge action. We discuss how it depends on a uniform external magnetic field, showing how it displays anisotropies with respect to the magnetic field direction. Moreover, we compare the observed anisotropy pattern with that of the static quark-antiquark potential we obtained in our previous works.
