The $I$ = 1/2 and 3/2 $K-\pi$ scattering length with domain wall fermions at physical pion mass with all-to-all propagators

Nils Asmussen, Felix Erben, Jonathan Flynn +3

We present our calculations for the $I$ = 1/2 and 3/2 $K-\pi$ s-wave scattering length with physical quark masses, extracted from the interaction energy of Euclidean two-point functi…
