摘要:

我们研究了与矢量玻色子融合相关的标准模型有效场论的六维算子的影响以及LHC中相关的希格斯玻色子的产生。我们目前的预测在下一个领先的顺序精度QCD,包括匹配部分子阵雨,并依赖于全自动模拟。我们表明,随后减少的理论不确定性的重要性,以提高可能的歧视之间的有效场论和标准模型的结果,我们证明了威尔逊系数值的范围内允许的全球适合LEP和LHC运行~I数据可以进一步限制LHC运行~II未来的结果。

英文摘要:

We study the impact of dimension-six operators of the standard model effective field theory relevant for vector-boson fusion and associated Higgs boson production at the LHC. We present predictions at the next-to-leading order accuracy in QCD that include matching to parton showers and that rely on fully automated simulations. We show the importance of the subsequent reduction of the theoretical uncertainties in improving the possible discrimination between effective field theory and standard model results, and we demonstrate that the range of the Wilson coefficient values allowed by a global fit to LEP and LHC Run~I data can be further constrained by LHC Run~II future results.
