  • Charmonium spectral functions in Nf=2 QCD 

    PEARDON, MICHAEL JAMES; SKULLERUD, JONIVAR (Proceedings of Science, 2005)
    We report on a study of charmonium at high temperature in 2-flavour QCD. This is the first such study with dynamical fermions. Using an improved anisotropic lattice action, spectral functions are extracted from correlators ...
  • Charmonium spectroscopy on dynamical anisotropic lattices 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Elsevier, 2006)
    We present a first study of the charmonium spectrum on Nf = 2 dynamical, anisotropic lattices. We take advantage of all-to-all quark propagators to build spatially extended interpolating operators to increase the overlap ...
  • Improving Algorithms to Compute All Elements of the Lattice Quark Propagator 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Elsevier, 2005)
    We present a new exact algorithm for estimating all elements of the quark propagator. The advantage of the method is that the exact all-to-all propagator is reproduced in a large but finite number of inversions. The ...
  • Mesons at high temperature in Nf=2 QCD 

    PEARDON, MICHAEL JAMES; SKULLERUD, JONIVAR (American Physical Society, 2006)
    We report first results for spectral functions of charmonium in 2-flavour QCD. The spectral functions are determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/ and c are found ...
  • Practical all-to-all propagators for lattice QCD 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Elsevier, 2005)
    A new method for computing all elements of the lattice quark propagator is proposed. The method combines the spectral decomposition of the propagator, computing the lowest eigenmodes exactly, with noisy estimators which ...
  • Static-light hadrons on a dynamical anisotropic lattice 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Proceedings of Science, 2005)
    We present preliminary results for the static-light meson and baryon spectra for Nf = 2 QCD. The study is performed on an anisotropic lattice and uses a new all-to-all propagator method allowing us to determine particle ...
  • Static-light matrix elements on a dynamical antisotropic lattice 

    PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE; SKULLERUD, JONIVAR (Elsevier, 2005)
    The static-light matrix element needed to determine fB is studied on an anisotropic lattice with Nf = 2. The improvement in precision due to stout links and all-to-all propagators is investigated.
