DESCRIPTION:Speakers: Anton Rebhan (Vienna University of Technology (TU Wi
 en))\n\nConventional hadronic models with a finite number of resonances ar
 e incapable of satisfying short-distance constraints on hadronic light-by-
 light scattering such as the longitudinal Melnikov-Vainshtein (MV) constra
 int derived from the chiral anomaly and its one-loop exactness. I review h
 ow minimal models of holographic QCD naturally solve this problem by their
  infinite tower of resonances\, and to what extent models which include th
 e axial U(1) anomaly lead to a realistic quantitative description. Transve
 rse short-distance constraints that are not fixed by the anomaly are only 
 partially solved and point to the importance of tensor meson contributions
