$B$ Meson Matrix Elements from Various Heavy Quark Effective Theories

Abstract

Various properties of heavy-light mesons are determined, including decay constants, the $B_B$-parameter, and the Isgur-Wise function. The heavy (bottom) quark is simulated with the static, NRQCD and/or (fixed-velocity) lattice-HQET effective theories, using optimally-smeared sources as produced by the ``Maximal Operator Smearing Technique''.
