Bs mesons using staggered light quarks

Abstract Last year we proposed using staggered fermions as the light quarks, combined with nonrelativistic heavy quarks, in simulations of heavy-light mesons. A first round of tests which focuses on the B s meson has been completed using quenched lattices, and results are presented here for the kinetic B s mass, the B s * − B s splitting, and fBa. The next project, already underway, is to compute the B and B s decay constants and spectra on the n f = 2 + 1 and 3 MILC lattices. We report on progress with one set of these configurations.
