Description
We present a lattice QCD calculation of the K⁺n scattering length and effective range in the S-wave channel. This study employs the CLQCD gauge configurations (ensemble F24P29) with a pion mass of Mπ ≈ 300 MeV and a lattice spacing of a ≈ 0.1053 fm. By computing the finite-volume energy spectrum of the KN system—obtaining 5-6 distinct energy levels in both the center-of-mass frame and several moving frames—and applying the Lüscher finite-volume formalism, we extract the corresponding scattering phase shifts. From these phase shifts, the scattering length and effective range are determined.
