Chiral extrapolation and determination of low-energy constants from lattice data

Gerhard Ecker, Pere Masjuan, Helmut Neufeld

We propose analytic approximations of chiral SU(3) amplitudes for the extrapolation of lattice data to the physical meson masses. The method allows the determination of NNLO low-en…
