Abstract
We review briefly old problems of QCD phenomenology arising in attempts to relate hadronic properties to the properties of the vacuum fields. In terms of QCD sum rules, quadratic corrections to the parton model defy standard picture of soft confining fields. In direct lattice measurements, with high resolution, confining fields do not look soft either. Dual approach to Yang‐Mills theories, known as AdS/QCD correspondence naturally resolves these paradoxes. In particular, quadratic corrections are parametrized in terms of a single number in an explicitly gauge invariant way. Confining fields on the lattice which look as low‐dimensional vacuum defects are identified with magnetic strings.
