Dynamical Simulations with Highly Improved Staggered Quarks
K. Y. Wong, R. M. Woloshyn
It is well established that lattice artifacts can be suppressed substantially by the use of SU(3)-projected smeared links in the fermion action. An example is the Highly Improved S…
B meson decays from moving-NRQCD on fine MILC lattices
C. T. H. Davies, G. P. Lepage, Kit Yan Wong
Lattice simulations of decays are problematic in the low region when the pion has to have large momentum in the lattice frame for a meson at rest or moving sl…
Perturbative Wilson loops from unquenched Monte Carlo simulations at weak couplings
Kit Yan Wong, Howard D. Trottier, R. M. Woloshyn
Perturbative expansions of several small Wilson loops are computed through next-to-next-to-leading order in unquenched lattice QCD, from Monte Carlo simulations at weak couplings.…
Systematics of Staggered Fermion Spectral Properties and Topology
Kit Yan Wong, R. M. Woloshyn
The spectral properties of a variety of improved staggered operators are studied in quenched QCD. The systematic dependence of the infrared eigenvalue spectrum on i) improvement in…
Static potential and local color fields in unquenched lattice QCD
Howard D. Trottier, Kit Yan Wong
String breaking by dynamical quarks in three-dimensional lattice QCD is analyzed through measurements of the potential and the local color-electric field strength generated by a st…
Topology and Staggered Fermion Action Improvement
Kit Yan Wong, R. M. Woloshyn
It is conventional wisdom that staggered fermions do not feel gauge field topology. However, the response of staggered fermion eigenmodes to the topology of the gauge field can dep…
