Electromagnetic splittings of hadrons from improved staggered quarks in full QCD
S. Basak, A. Bazavov, C. Bernard +10
We present our initial study of the electromagnetic splittings of charged and neutral mesons, and the violation of Dashen's theorem. Hadron masses are calculated on MILC N_f=2+1 QC…
The B -> pi l nu semileptonic form factor from three-flavor lattice QCD: A model-independent determination of |V(ub)|
Jon A. Bailey, C. Bernard, C. DeTar +17
We calculate the form factor f_+(q^2) for B-meson semileptonic decay in unquenched lattice QCD with 2+1 flavors of light sea quarks. We use Asqtad-improved staggered light quarks a…
Light pseudoscalar meson masses and decay constants from mixed action lattice QCD
Christopher Aubin, Jack Laiho, Ruth S. Van de Water
We calculate the light pseudoscalar decay constants, f_pi and f_K, and their ratio using domain wall valence quarks and 2+1 flavors of dynamical staggered quarks. Use of the MILC g…
K to pi and K to 0 in 2+1 Flavor Partially Quenched Chiral Perturbation Theory
C. Aubin, J. Laiho, S. Li +1
We calculate results for K to pi and K to 0 matrix elements to next-to-leading order in 2+1 flavor partially quenched chiral perturbation theory. Results are presented for both the…
The B -> D* l nu form factor at zero recoil from three-flavor lattice QCD: A model independent determination of |V_cb|
C. Bernard, C. DeTar, M. Di Pierro +16
We present the first lattice QCD calculation of the form factor for B-> D* l nu with three flavors of sea quarks. We use an improved staggered action for the light valence and sea…
Discretization effects and the scalar meson correlator in mixed-action lattice simulations
C. Aubin, Jack Laiho, Ruth S. Van de Water
We study discretization effects in a mixed-action lattice theory with domain-wall valence quarks and Asqtad-improved staggered sea quarks. At the level of the chiral effective Lagr…
