摘要：

We present the results of a computation of the topological susceptibility in the SU(3) Yang-Mills theory performed by employing the expression of the topological charge density operator suggested by Neuberger's r(o)(4)chi = 0.059(3), which corresponds to chi = (191 +/- 5 MeV)(4) if F-K is used to set the scale. Our result supports the Witten-Veneziano explanation for the large mass of the eta'.
