# Universality of the topological susceptibility in the SU(3) gauge theory

@article{Lscher2010UniversalityOT, title={Universality of the topological susceptibility in the SU(3) gauge theory}, author={Martin L{\"u}scher and Filippo Palombi}, journal={Journal of High Energy Physics}, year={2010}, volume={2010}, pages={1-12} }

The definition and computation of the topological susceptibility in non-abelian gauge theories is complicated by the presence of non-integrable short-distance singularities. Recently, alternative representations of the susceptibility were discovered, which are singularity-free and do not require renormalization. Such an expression is here studied quantitatively, using the lattice formulation of the SU(3) gauge theory and numerical simulations. The results confirm the expected scaling of the…
