Continuum Extrapolation of Moments of Nucleon Quark Distributions in Full QCD
LHPC, SESAM Collaborations, : +12
Moments of light cone quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD at and using Wilson fermions on $ 16^3 \tim…
Heavy-light meson decay constants with N_f=3
MILC Collaboration, C. Bernard, T. Burch +7
During the past year the MILC Collaboration has continued its study of heavy-light meson decay constants with three dynamical quarks. Calculations have been extended to a second la…
Modelling the quark propagator
P. O. Bowman, U. M. Heller, D. B. Leinweber +1
The quark propagator is at the core of lattice hadron spectrum calculations as well as studies in other nonperturbative schemes. We investigate the quark propagator with an improve…
Towards the Continuum Limit of the Overlap Quark Propagator in Landau Gauge
J. B. Zhang, F. D. R. Bonnet, P. O. Bowman +2
The properties of the momentum space quark propagator in Landau gauge are examined for the overlap quark action in quenched lattice QCD. Numerical calculations were done on two lat…
Exotic hybrid mesons from improved Kogut-Susskind fermions
C. Bernard, T. Burch, C. DeTar +6
We summarize our measurement of the mass of the exotic hybrid meson using an improved Kogut-Susskind action. We show results from both quenched and dynamical quark simulat…
High temperature QCD with three flavors of improved staggered quarks
The MILC Collaboration, C. Bernard, T. Burch +7
We present an update of our study of high temperature QCD with three flavors of quarks, using a Symanzik improved gauge action and the Asqtad staggered quark action. Simulations ar…
Chiral logs with staggered fermions
C. Aubin, C. Bernard, C. DeTar +5
We compute chiral logarithms in the presence of "taste" symmetry breaking of staggered fermions. The lagrangian of Lee and Sharpe is generalized and then used to calculate the logs…
Static hybrid quarkonium potential with improved staggered quarks
MILC Collaboration, C. Bernard, T. Burch +8
We are studying the effects of light dynamical quarks on the excitation energies of a flux tube between a static quark and antiquark. We report preliminary results of an analysis o…
Topological susceptibility with the improved Asqtad action
MILC Collaboration, C. Bernard, T. Burch +10
As a test of the chiral properties of the improved Asqtad (staggered fermion) action, we have been measuring the topological susceptibility as a function of quark masses for 2 + 1…
Light hadron properties with improved staggered quarks
C. Bernard, T. Burch, T. DeGrand +7
Preliminary results from simulations with 2+1 dynamical quark flavors at a lattice spacing of 0.09 fm are combined with earlier results at a=0.13 fm. We examine the approach to the…
Dynamics of the 2d Potts model phase transition
Alexander Velytsky, Bernd A. Berg, Urs M. Heller
The dynamics of 2d Potts models, which are temperature driven through the phase transition using updating procedures in the Glauber universality class, is investigated. We present…
Gluon Propagator on Coarse Lattices in Laplacian Gauges
P. O. Bowman, U. M. Heller, D. B. Leinweber +1
The Laplacian gauge is a nonperturbative gauge fixing that reduces to Landau gauge in the asymptotic limit. Like Landau gauge, it respects Lorentz invariance, but it is free of Gri…
Lattice Calculation of Heavy-Light Decay Constants with Two Flavors of Dynamical Quarks
The MILC Collaboration, C. Bernard, S. Datta +8
We present results for , , , and their ratios in the presence of two flavors of light sea quarks (). We use Wilson light valence quarks and Wils…
Lattice quark propagator with staggered quarks in Landau and Laplacian gauges
P. O. Bowman, U. M. Heller, A. G. Williams
We report on the lattice quark propagator using standard and improved Staggered quark actions, with the standard, Wilson gauge action. The standard Kogut-Susskind action has errors…
Overlap Quark Propagator in Landau Gauge
Frédéric D. R. Bonnet, Patrick O. Bowman, Derek B. Leinweber +2
The properties of the quark propagator in Landau gauge in quenched QCD are examined for the overlap quark action. The overlap quark action satisfies the Ginsparg-Wilson relation an…
Moments of Nucleon Light Cone Quark Distributions Calculated in Full Lattice QCD
LHPC Collaboration, SESAM Collaboration, D. Dolgov +11
Moments of the quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD. Calculations of proton matrix elements of operators corresponding t…
