TL;DR
This study precisely measures the topological susceptibility in SU(3) pure gauge theory through high-statistics lattice simulations, achieving continuum and infinite volume limits to provide accurate physical results.
Contribution
It presents the first high-precision determination of the SU(3) topological susceptibility with combined continuum and infinite volume extrapolations.
Findings
Topological susceptibility: chi_{top}r_0^4=0.0524(7)(6)
Physical value: chi_{top}^{1/4}=193(1)(8)MeV
Results include continuum and infinite volume limits
Abstract
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 chi_{top}r_0^4=0.0524(7)(6) which translates into chi_{top}^{1/4}=193(1)(8)MeV with the second error exclusively due to the intrinsic scale ambiguity.
