DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/104/">
 Two dimensional QCD as a string theory</a>\nby Ofer Aharony (Weizmann and 
 IAS) as part of NHETC Seminar\n\n\nAbstract\n50 years after the duality of
  large N gauge theories to string theories was suggested\, we still do not
  have a constructive method to find the string dual of a given gauge theor
 y. I will review work in progress on two approaches to understanding this\
 , in what should perhaps be the simplest case\, namely two dimensional gau
 ge theories. The first approach uses perturbation theory to obtain an effe
 ctive stringy description of the high-energy states of 2d QCD with very ma
 ssive adjoint fermions. The second approach starts from finding a good wor
 ldsheet description for the string dual to the two dimensional pure Yang-M
 ills theory\, following past work by Gross-Taylor\, Cordes-Moore-Ramgoolam
 \, and Horava\; in the future we hope to add to it boundaries (quarks in t
 he fundamental representation) and/or extra particles on the worldsheet (a
 djoint matter fields).\n
