Theta dependence in the large N limit

High Energy Physics - Lattice 2017-02-06 v1 High Energy Physics - Theory

Abstract

Studies of the large NN behaviour of the topological properties of gauge theories typically focused on the large NN scaling of the topological susceptibility. A much more difficult task is the study of the behaviour of higher cumulants of the topological charge in the large NN limit, which up to now remained elusive. We will present first results confirming the expected large NN scaling of the coefficient commonly denoted by b2b_2, related to the kurtosis of the topological charge.
