Charmed meson decay constants in three-flavor lattice QCD
C. Aubin, C. Bernard, C. DeTar +18
We present the first lattice QCD calculation with realistic sea quark content of the D^+ meson decay constant f_{D^+}. We use the MILC Collaboration's publicly available ensembles…
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…
D_s spectrum and leptonic decays with Fermilab heavy quarks and improved staggered light quarks
Massimo di Pierro, Aida X. El-Khadra, Steven Gottlieb +5
We present preliminary results for the D_s meson spectrum and decay constants in unquenched lattice QCD. Simulations are carried out with 2+1 dynamical quarks using gauge configura…
Properties of charmonium in lattice QCD with 2+1 flavors of improved staggered sea quarks
Massimo di Pierro, Aida X. El-Khadra, Steven Gottlieb +6
We use the dynamical gluon configurations provided by the MILC collaboration in a study of the charmonium spectrum and psi leptonic width. We examine sea quark effects on mass spli…
Semileptonic decays of mesons in unquenched lattice QCD
Masataka Okamoto, Massimo di Pierro, Aida X. El-Khadra +6
We present our preliminary results for semileptonic form factors of mesons in unquenched lattice QCD. Simulations are carried out with dynamical quarks using gauge co…
Charmonium with three flavors of dynamical quarks
Massimo Di Pierro, Aida X. El-Khadra, Steven Gottlieb +5
We present a calculation of the charmonium spectrum with three flavors of dynamical staggered quarks from gauge configurations that were generated by the MILC collaboration. We use…
