Query: Color screening in flux tubes and in the color Coulomb potential from
  the QCD Field Correlators   Colorelectric and Colormagnetic structure of the flux tubes, connecting heavy
quark and antiquark, is investigated in the framework of the Field Correlator
method which describes all resulting fields in terms of correlators $D^E$ and
$D^E_1$. The latter have been computed via gluelumps, which allows to predict
the resulting distribution of color fields $\mathbf{E} (\mathbf{r}),$ and
colormagnetic currents $\mathbf{k} (\mathbf{r})$ in the flux tubes. It is
shown, that at large distances $r\gg \lambda \approx 0.2$ fm the whole
structure of fields and relations between them is similar to that of the dual
superconductor theory, but the basic dynamics, including small distances, is
given by field correlators of the real stochastic vacuum. The important
contradiction between the strong screening of color fields in the width of flux
tubes and almost no screening in the perturbative $Q\bar Q$ potential is
resolved.
