Highly Excited Hadrons in QCD and Beyond
High Energy Physics - Phenomenology

Abstract
I discuss two issues related to high "radial" excitations which attracted much attention recently: (i) chiral symmetry restoration in excited mesons and baryons, and (ii) universality of the rho-meson coupling in QCD and AdS/QCD. New results are reported and a curious relation between an AdS/QCD formula and 1977 Migdal's proposal is noted.
