A note on W symmetry of N=2 gauge theory

High Energy Physics - Theory 2012-06-21 v2

Abstract

The AGT correspondence indicates N=2\mathcal{N}=2 gauge theory possesses of W algebra symmetry. We study how the conformal block of Toda CFT gives the expectation value of Casimir operators of gauge theory. The A2A_2 Toda CFT with W3W_3 symmetry is taken as the main example.
