Heavy-light mesons with staggered light quarks
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 Bs meson kinetic mass, the hyperfine and 1P-1S splittings in Bs, and the decay constant fBs are calculated and compared to previous quenched lattice studies. An important technical detail, Bayesian curve-fitting, is discussed at length.
