Leptonic decay constants f_Ds and f_D in three flavor lattice QCD
J. N. Simone, C. Aubin, C. Bernard +21
We determine the leptonic decay constants in three flavor unquenched lattice QCD. We use O(a^2)-improved staggered light quarks and O(a)-improved charm quarks in the Fermilab heavy…
The scaling dimension of low lying Dirac eigenmodes and of the topological charge density
MILC Collaboration, C. Aubin, C. Bernard +11
As a quantitative measure of localization, the inverse participation ratio of low lying Dirac eigenmodes and topological charge density is calculated on quenched lattices over a wi…
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…
