    • A novel method for evaluating correlation functions in lattice hadron spectroscopy 

      Peardon, Michael (2010)
      We describe a new approach for evaluating hadronic correlation functions which combines Laplacian-Heaviside quark smearing with a stochastic estimator of quark propagators. This method utilizes noise ...

    • Phase shift with LapH propagators 

      Peardon, Michael (2010)
      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 ...
