Pion-pion scattering phase shifts with the stochastic LapH method

Abstract

Progress in calculating scattering phase shifts on $N_f=2+1$ anisotropic clover Wilson lattices is described. The stochastic LapH method facilitates computations in large volumes and for light pion masses. Results for pion masses down to 240 MeV, keeping $m_{\pi }L>4$, are presented.
