Elastic I = 1/2, s- and p-wave Kπ scattering amplitudes are simultaneously calculated using a Lüscher style analysis on a single ensemble of dynamical Wilson-clover fermions at mπ ∼ 230 MeV. Partial wave mixing due to the reduced rotational symmetries of the finite volume is included up to ` = 2. We also present finite-volume QCD spectra on two large anisotropic lattices (323 ×256, 243 ×128) with mπ ∼ 230, 390 MeV respectively. In each symmetry channel, a large basis of one- and two-hadron interpolating operators is employed with all-to-all quark propagation treated using the stochastic LapH method.
