SUMMARY:Exact symmetries and threshold states in two-dimensional models for QCD
DESCRIPTION:Speaker: Silviu Pufu (Princeton University) \nTitle: Exact symmetries and threshold states in two-dimensional models for QCD \nAbstract: Two-dimensional QCD models form an interesting playground for studying phenomena such as confinement and screening.  In this talk I will describe one such model\, namely a 2d SU(N) gauge theory with an adjoint and a fundamental fermion\, and explain how to compute the spectrum of bound states using discretized light-cone quantization at large N.  Surprisingly\, the spectrum of the discretized theory exhibits a large number of exact degeneracies\, for which I will provide two different explanations.  I will also discuss how these degeneracies provide a physical picture of confinement in 2d QCD with just a massless adjoint fermion.  This talk is based on joint work with R. Dempsey and I. Klebanov.
