7 Nov 2002 | | Journal: | Phys.Rev. D67 (2003) 054505 | | Subject: | hep-lat | | Affiliation: | Ohio State), Christine T.H. Davies (Glasgow), G. Peter Lepage (Cornell), and Howard D. Trottier (Simon Fraser | | Abstract: | We demonstrate the viability of improved staggered light quarks in studies of heavy-light systems. Our method for constructing heavy-light operators exploits the close relation between naive and staggered fermions. The new approach is tested on quenched configurations using several staggered actionsn combined with nonrelativistic heavy quarks. The B_s meson kinetic mass, the hyperfine and 1P-1S splittings in B_s, and the decay constant f_{B_s} are calculated and compared to previous quenched lattice studies. An important technical detail, Bayesian curve-fitting, is discussed at length. | | Source: | arXiv, hep-lat/0211014 | | Services: | Forum | Review | PDF | Favorites | |
