摘要:

我们报告使用费米实验室重夸克计算重夸克质量。重奇异介子质量的晶格计算与单圈(自动)晶格微扰理论相结合,以达到夸克质量。介子是由费米实验室重夸克和交错轻夸克构成的。我们使用的MILC合奏在三个晶格间距和海夸克质量比为$m_{\rm u,d} / m_{\rm s} = 0.1$至0.4。在势减方案中给出了底夸克的初步结果。

英文摘要:

We report on heavy quark mass calculations using Fermilab heavy quarks. Lattice calculations of heavy-strange meson masses are combined with one-loop (automated) lattice perturbation theory to arrive at the quark mass. Mesons are constructed from Fermilab heavy quarks and staggered light quarks. We use the MILC ensembles at three lattice spacings and sea quark mass ratios of $m_{\rm u,d} / m_{\rm s} = 0.1$ to 0.4. Preliminary results for the bottom quark are given in the potential subtracted scheme.
