The Ι = 1/2 and 3/2 Κ-π scattering length with domain wall fermions at physical pion mass with all-to-all propagators
The Ι = 1/2 and 3/2 Κ-π scattering length with domain wall fermions at physical pion mass with all-to-all propagators
We present our calculations for the Ι = 1/2 and 3/2Κ\π s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functions. We use the domain wall fermion action with physical quark masses at a single lattice spacing. We are specifically interested in the systematic effects due to around-the-world terms on the overall determination of the scattering length. We present our progress and discuss the various systematic effects in our preliminary results.

Abstract
We present our calculations for the Ι = 1/2 and 3/2Κ\π s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functions. We use the domain wall fermion action with physical quark masses at a single lattice spacing. We are specifically interested in the systematic effects due to around-the-world terms on the overall determination of the scattering length. We present our progress and discuss the various systematic effects in our preliminary results.
