内容記述タイプ | Abstract | |||||
内容記述 | We investigate the scaling behavior of the B meson decay constant fB and fBs, at β=5.7, 5.9, 6.1, employing the NRQCD heavy quark action and the clover light quark action. Mixing effect from dimension-4 operator in the heavy-light axial-vector current is studied, and we find that the a dependence of fB is significantly reduced. Our preliminary result for the decay constants in the quenched approximation is fB=162(+35?18) MeV, fBs=190(+40?19) MeV, and fBs/fB=1.18(+6?6). | |||||
