High Energy Theory Informal Seminar - Daniele Dorigoni, Cambridge U.K. - "The Large-N Limit of 3d Super YM and Bosonization"
In the large N limit, gauge theories compactified on $R^{d-k} \times (S^1)^k$ are independent of the $S^1$ radii, provided that center symmetry remains unbroken. Volume independence holds for arbitrary circle size L, therefore we can match a set of correlation functions in the theory on $R^d$ to the corresponding observables in the reduced $R^{d-k}$ theory.
We focus our attention to 3D SYM reduced to 2D and show explicitly how the compact direction is encoded in the color degrees of freedom.
By combining volume independence with results from CFTs and Kac-Moody algebras we will obtain a bosonized description of the starting 3D theory. As an application we compute the k-string tension and then conclude with some remarks about 3D Chern-Simons-YM.
