Phase shift with LapH propagators (2010)

Abstract The pion-pion scattering phase shift is computed using LapH propagators. The LapH method for computing quark propagators is used to form two-particle correlation functions with a number of different operators. Excited state energies of two-particle states on 2+1 dynamical, anisotropic lattices (mπ∼390MeV) are computed to determine the phase shift in the I=2 channel. The signal for t-to-t diagrams for the I=0 channel are also presented to demonstrate the efficacy of the stochastic LapH method.
