标题： RESULTS FOR THE B-MESON DECAY CONSTANT FROM THE APE COLLABORATION

摘要： 在静态极限下，使用威尔逊和扭结作用量计算了B介子的衰变常数。 我们表明，我们的结果受激发态污染以及有限格点间距效应的影响最多与统计不确定性同阶。 将我们的结果与其他研究的结果进行了比较。 还给出了$f^{stat}_{B_S}/f^{stat}_B$和$M_{B_S} - M_B$的值。 显示英文摘要

摘要： The decay constant for the B-meson in the static limit is calculated using the Wilson and clover actions at various lattice spacings. We show that both the contamination of our results by excited states and the effects finite lattice spacing are at most the order of the statistical uncertainties. A comparison is made of our results and those obtained in other studies. Values for $f^{stat}_{B_S}/f^{stat}_B$ and $M_{B_S} - M_B$ are also given.
