A Possible Aoki Phase for Staggered Fermions
C. Aubin, Qinghai Wang
The phase diagram for staggered fermions is discussed in the context of the staggered chiral Lagrangian, extending previous work on the subject. When the discretization errors are…
Semileptonic D->pi/K and B->pi/D decays in 2+1 flavor lattice QCD
M. Okamoto, C. Aubin, C. Bernard +17
We present results for form factors of semileptonic decays of and mesons in 2+1 flavor lattice QCD using the MILC gauge configurations. With an improved staggered action fo…
Topological susceptibility with three flavors of staggered quarks
C. Aubin, C. Bernard, Brian Billeter +8
As one test of the validity of the staggered-fermion fourth-root determinant trick, we examine the suppression of the topological susceptibility of the QCD vacuum in the limit of s…
Staggered Chiral Perturbation Theory with Heavy-Light Mesons
C. Aubin, C. Bernard
We merge heavy quark effective theory with staggered chiral perturbation theory to calculate heavy-light (B, D) meson quantities. We present results at NLO for the meson dec…
Light pseudoscalar decay constants, quark masses, and low energy constants from three-flavor lattice QCD
MILC Collaboration, C. Aubin, C. Bernard +8
As part of our program of lattice simulations of three flavor QCD with improved staggered quarks, we have calculated pseudoscalar meson masses and decay constants for a range of va…
Lattice Gauge Fixing as Quenching and the Violation of Spectral Positivity
C. Aubin, Michael C. Ogilvie
Lattice Landau gauge and other related lattice gauge fixing schemes are known to violate spectral positivity. The most direct sign of the violation is the rise of the effective mas…
