    • Estimated errors in |Vcd|/|Vcs| from semileptonic D decays 

      RYAN, SINEAD MARIE (Elsevier, 1999)
      We estimate statistical and systematic errors in the extraction of the CKM ratio |Vcd|/|Vcs| from exclusive D-meson semileptonic decays using lattice QCD and anticipated new experimental results.

    • Heavy hadrons on an anisotropic lattice 

      PEARDON, MICHAEL JAMES; RYAN, SINEAD MARIE (Elsevier, 2004)
      Results from simulations of quarkonia and heavy-light mesons on an anisotropic lattice are presented. The improved quark action and action-parameter tuning used in this study are discussed.

    • Progress in leptonic and semileptonic decays in lattice QCD 

      RYAN, SINEAD MARIE (American Physical Society, 1999)
      The status of lattice calculations of heavy quark phenomenology is reviewed. Particular emphasis is placed on the understanding and control of the calculational uncertainties. The ensuing implications for constraining ...

    • Quenched QCD with O(a) improvement: The spectrum of light hadrons 

      RYAN, SINEAD MARIE (American Physical Society, 2000)
      We present a comprehensive study of the masses of pseudoscalar and vector mesons, as well as octet and decuplet baryons computed in O(a)-improved quenched lattice QCD. Results have been obtained using the nonperturbative ...

    • Soft covariant gauges on the lattice 

      RYAN, SINEAD MARIE (2008-10-08)
      We present an exploratory study of a one-parameter family of covariant, nonperturbative lattice gauge-fixing conditions that can be implemented through a simple Monte Carlo algorithm. We demonstrate that at the numerical ...
