9 Sep 2002 | | Subject: | hep-lat | | Affiliation: | Ohio State), G. Peter Lepage (Cornell), Christine Davies (Glasgow), and Howard Trottier (Simon Fraser | | 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 f_{B_s}. 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. | | Source: | arXiv, hep-lat/0209096 | | Services: | Forum | Review | PDF | Favorites | |
