论文摘要
我们研究了标准模型有效田间理论（SMEFT）中通过向量 - 玻色子融合（VBF）在高横向动量（SMEFT）中研究Higgs玻色子的产生。我们发现，来自四个独立操作员组合的贡献在此限制下占主导地位。这些是控制高能量双二博工艺的“高能量原则”，包括希格斯 - 斯特朗。我们为希格斯玻色子的双刺衰变模式以及由ditau通道产生的三个最终状态执行了详细的对撞机模拟。使用SMEFT贡献相对于标准模型（SM）贡献的二次增长，我们对这些操作员的界限非常严格，这些界限超过了LEP实验的相应界限。
We study the production of Higgs bosons at high transverse momenta via vector-boson fusion (VBF) in the Standard Model Effective Field Theory (SMEFT). We find that contributions from four independent operator combinations dominate in this limit. These are the same `high energy primaries' that control high energy diboson processes, including Higgs-strahlung. We perform detailed collider simulations for the diphoton decay mode of the Higgs boson as well as the three final states arising from the ditau channel. Using the quadratic growth of the SMEFT contributions relative to the Standard Model (SM) contribution, we project very stringent bounds on these operators that far surpass the corresponding bounds from the LEP experiment.
