On the exact R charge for N=2 CS theories [PDF]
A. AmaritiRecently it was argued that the exact R charge for three dimensional N=2 supersymmetric field theories extremizes the partition function localized on S^3. In this paper we check this conjecture by computing the R charge for SU(N)_k YM CS gauge theories at large k for many representations, and we test the agreement with the perturbative results.View original: http://arxiv.org/abs/1103.1618
