Precision Study of the Topological Susceptibility in the Continuum

Presenter: Thorsten Kurth — BU Wuppertal

We determine the topological susceptibility in the SU(3) pure gauge theory. We perform a series of high-statistics lattice studies and take the combined continuum and infinite volume limit. We find χtop r04=0.0524(7)(6), which translates into χtop1/4=193(1)(8) MeV with the second error exclusively due to the intrnsic scale ambiguity.
