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…
