希格斯玻色子质量曾经是标准模型中电弱贡献的唯一未知输入参数。它在图中的两个循环级别进入,例如,top循环,,orexchange.我们重新评估这些贡献,提供解析表达式和精确的数值结果希格斯玻色子质量最近在大型强子对撞机测量。我们的最终结果为完整的标准模型电弱贡献,其余的理论误差来自未知的三圈贡献和强子不确定性。
The Higgs-boson mass used to be the only unknown input parameter of the electroweak contributions toin the Standard Model. It enters at the two-loop level in diagrams with, e.g., top loops,, orexchange. We reevaluate these contributions, providing analytic expressions and exact numerical results for the Higgs-boson mass recently measured at the LHC. Our final result for the full Standard Model electroweak contributions is, where the remaining theory error comes from unknown three-loop contributions and hadronic uncertainties.
