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

Ecker, Gerhard, Masjuan, Pere, Neufeld, Helmut

Understand

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-energy constants in a controllable fashion.
  • We test the approach with recent lattice data for the ratio F_K/F_pi of meson decay constants.
