AI中文摘要：
我们开展了大型强子对撞机（LHC）中存在反常耦合时矢量玻色子融合（VBF）产生希格斯玻色子的详细模拟研究。该分析采用Herwig事例产生器与VBFNLO对接，运用多喷注合并方案，将希格斯玻色子加2喷注和3喷注多重性的次领头阶（NLO）精确矩阵元，与希格斯玻色子加4喷注多重性的领头阶（LO）精确矩阵元相结合。我们研究了匹配与合并设置，以将这些硬散射过程与QCD部分子簇射一致地结合起来。最后，我们证明了在这些框架下，方位角可观测量对QCD辐射修正具有稳健性。
英文摘要：
We present the results of a detailed simulation study of Higgs boson production via vector boson fusion (VBF) at the Large Hadron Collider (LHC) in the presence of anomalous couplings. The analysis utilizes the Herwig event generator interfaced with VBFNLO, employing a multi-jet merging scheme that combines NLO accurate matrix elements for Higgs plus 2- and 3-jet multiplicities with LO accurate matrix elements for Higgs plus 4-jet multiplicities. We investigate both matching and merging setups to consistently combine these hard scattering processes with QCD parton showers. Finally, we demonstrate the robustness of azimuthal angle observables against QCD radiative corrections across these frameworks.
