运行I数据的基础上，我们提出了一个全面的分析希格斯耦合。这是第一次SFITTER分析包括希格斯胶子和顶部汤川耦合，希格斯衰变为不可见粒子，和壳外希格斯测量的独立测试。观察到的希格斯玻色子与标准模型完全一致，无论是在耦合修正还是有效场论方面。仅基于希格斯总速率，使用这两种方法的结果基本上是等价的，除了在参数空间中由有效算子引起的强相关性。这些相关性可以通过额外的实验输入来控制，即运动学分布。包括运动学分布的典型运行我达到弱相互作用的新物理现在达到300至500 GeV。
Based on Run I data we present a comprehensive analysis of Higgs couplings. For the first time this SFitter analysis includes independent tests of the Higgs-gluon and top Yukawa couplings, Higgs decays to invisible particles, and off-shell Higgs measurements. The observed Higgs boson is fully consistent with the Standard Model, both in terms of coupling modifications and effective field theory. Based only on Higgs total rates the results using both approaches are essentially equivalent, with the exception of strong correlations in the parameter space induced by effective operators. These correlations can be controlled through additional experimental input, namely kinematic distributions. Including kinematic distributions the typical Run I reach for weakly interacting new physics now reaches 300 to 500 GeV.
