The calculation is performed using a 20³ × 40 dynamical FLIC ensemble with lattice spacing 0.126 fm at a range of pion masses; the effect of vacuum instanton content is compared at a common pion mass of 350 MeV. We find little evidence that the instanton effect is as significant as models would suggest. In fact, the direct instanton-induced effect cannot be seen at all.en© Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike LicenceConference paper002012699310.22323/1.164.02562-s2.0-8503008536820364Kamleh, W.
