- W3106185969 abstract "A toy model is proposed for four dimensional non-abelian gauge theories coupled to a large number of fermionic degrees of freedom. As the number of flavors is varied the gauge theory may be confining, walking or conformal. The toy model mimicking this feature is the two dimensional O(3) sigma model with a ϑ-term. For all ϑ the model is asymptotically free. For small ϑ the model is confining in the infra red, for ϑ = π the model has a non-trivial infra red fixed point and consequently for ϑ slightly below π the coupling walks. The first step in investigating the notoriously difficult systematic effects of the gauge theory in the toy model is to establish non-perturbatively that the ϑ parameter is actually a relevant coupling. This is done by showing that there exist quantities that are entirely given by the total topological charge and are well defined in the continuum limit and are non-zero, despite the fact that the topological susceptibility is divergent. More precisely it is established that the differences of connected correlation functions of the topological charge (the cumulants) are finite and non-zero and consequently there is only a single divergent parameter in Z (ϑ) but otherwise it is finite. This divergent constant can be removed by an appropriate counter term rendering the theory completely finite even at ϑ > 0." @default.
