Width difference of the B_s mesons from lattice QCD
Get PDFWe extend our previous studies to calculate the B meson B parameters B_B and
B_S on the lattice, and present an update of the results for the B_s meson
width difference. We perform an extensive study of systematic errors in the
quenched calculation of the B-parameters, and find that the systematic errors
are in good control using the NRQCD action for heavy quark. We also report our
preliminary results from unquenched simulations.Comment: 4 pages, 3 figures; to appear in the Proceedings of the 4th

Full text linkWe report on lattice calculations of the meson decay constant and the
B-parameters using the NRQCD action for heavy quark. We performed a set of
calculations at three lattice spacings in the quenched approximation in order
to investigate the systematic uncertainty associated with the lattice
discretization. Our results indicate that the systematic error is under good
control for f_B and B_B. We also present preliminary results from our
unquenched simulation.Comment: 4 pages, 3 figures; to appear in the Proceedings of the 4th
