论文摘要
我发现标准模型中QCD中领先顺序的三环校正对希格斯，W和Z玻色子的物理质量的校正。结果仅作为$ \ overline {\ rm {ms}} $ lagrangian参数的函数，使用无tadpole的方案来实现真空期望值。在每种情况下，计算出的质量对重新归一化量表的依赖性小于当前的实验不确定性。对于希格斯玻色子质量，新结果是最新结果，而$ w $和$ z $的结果是良好的数值协议，在壳和混合方案中相应的结果。这些结果现在包含在SMDR（维度正则化）计算机代码中。
I find the three-loop corrections at leading order in QCD to the physical masses of the Higgs, W, and Z bosons in the Standard Model. The results are obtained as functions of the $\overline{\rm{MS}}$ Lagrangian parameters only, using the tadpole-free scheme for the vacuum expectation value. The dependences of the computed masses on the renormalization scale are found to be smaller than present experimental uncertainties in each case. In the case of the Higgs boson mass, the new result is the state-of-the-art, while the results for $W$ and $Z$ are in good numerical agreement with corresponding results in the on-shell and hybrid schemes. These results are now included in the SMDR (Standard Model in Dimensional Regularization) computer code.
