Description
Elastic $I=1/2$, $s$- and $p$-wave $K\pi$ scattering amplitudes are simultaneously
calculated using a Lüscher style analysis on a single ensemble of dynamical
Wilson-clover fermions at $m_\pi \sim 230$MeV. Partial wave mixing due the reduced
rotational symmetries of the finite volume is included up to $\ell=2$.
We also present finite-volume QCD spectra on two large anisotropic lattices
($32^3\times256$, $24^3\times128$) with $m_\pi \sim 230, 390$MeV.
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.
