Title: Topological susceptibility in the SU(3) gauge theory

Abstract

We compute the topological susceptibility for the SU(3) Yang-Mills theory by employing the expression of the topological charge density operator suggested by Neuberger's fermions. In the continuum limit we find r{sub 0}{sup 4}{chi} = 0.059(3), which corresponds to {chi} = (191 {+-} 5 MeV)4 if FK is used to set the scale. Our result supports the Witten-Veneziano explanation for the large mass of the {eta}'. Comments on the large-volume distribution of the topological charge are presented.
