Title: Restoration of QCD classical symmetries in excited hadrons

Abstract

Restoration of chiral and U(1)A symmetries in excited hadrons is reviewed. A connection of these restorations with the semiclassical regime in highly excited hadron is discussed. A solvable confining field-theoretical toy model that exhibits chiral restoration is presented. Implications of the string description of the highly excited hadrons that suggests an additional dynamical symmetry of the spectra on the top of U(2)L U(2)R are presented.
