Analytic Approximations for the Extrapolation of Lattice Data
arXiv:1011.5750 · doi:10.1063/1.3536547
Abstract
We present analytic approximations of chiral SU(3) amplitudes for the extrapolation of lattice data to the physical masses and the determination of Next-to-Next-to-Leading-Order low-energy constants. Lattice data for the ratio F_K/F_pi is used to test the approximation proposed.
