本文在两个动力学非微扰改进的Wilson夸克的CLS格点上,对非微扰重整化的b夸克质量和B介子衰变常数进行了新的分析。此更新纳入了额外的轻夸克质量和晶格间距在大的物理体积,以改善手征外推,并达到连续极限。我们采用的重夸克有效理论(HQET)是在ALPHA合作组多年来发展的QCD和HQET匹配的基础上发展起来的,它包括了1/m_B项和非微扰系数。
We present an updated analysis of the non-perturbatively renormalized b-quark mass and B meson decay constant based on CLS lattices with two dynamical non-perturbatively improved Wilson quarks. This update incorporates additional light quark masses and lattice spacings in large physical volume to improve chiral extrapolations and to reach the continuum limit. We use Heavy Quark Effective Theory (HQET) including 1/m_b terms with non-perturbative coefficients based on the matching of QCD and HQET developed by the ALPHA collaboration during the past years.
