Electromagnetic contributions to pseudoscalar masses
S. Basak, A. Bazavov, C. Bernard +16
We report on the calculation by the MILC Collaboration of the electromagnetic effects on kaon and pion masses. These masses are computed in QCD with dynamical (asqtad staggered) qu…
Status of the MILC calculation of electromagnetic contributions to pseudoscalar masses
S. Basak, A. Bazavov, C. Bernard +16
We calculate pseudoscalar masses on gauge configurations containing the effects of 2+1 flavors of dynamical asqtad quarks and quenched electromagnetism. The lattice spacings vary f…
Adaptive Multigrid Algorithm for the QCD Dirac-Wilson Operator
J. Brannick, R. C. Brower, M. A. Clark +2
We present a new multigrid solver that is suitable for the Dirac operator in the presence of disordered gauge fields. The key behind the success of the algorithm is an adaptive pro…
High-Precision Lattice QCD Confronts Experiment
C. T. H. Davies, E. Follana, A. Gray +23
We argue that high-precision lattice QCD is now possible, for the first time, because of a new improved staggered quark discretization. We compare a wide variety of nonperturbative…
From chiral Random Matrix Theory to chiral Perturbation Theory
J. C. Osborn, D. Toublan, J. J. M. Verbaarschot
We study the spectrum of the QCD Dirac operator by means of the valence quark mass dependence of the chiral condensate in partially quenched Chiral Perturbation Theory (pqChPT) in…
