Comprison of lattice and chiral perturbation theory calculations of pion scattering lengths
Abstract
I compare the lattice calculation of Fukugita et al. for the pion Swave scattering lengths to the predictions of Chiral Perturbation Theory to two loop accuracy. I comment on the use of this comparison to extract the Chiral Perturbation Theory low energy constants.
