论文摘要
我们通过VBF流程VBF-VH研究了与向量（$ v = w，z $）的关联中希格斯的生产。在标准模型（SM）中，此过程在$ W $和$ z $介导的过程之间表现出树级的破坏性干扰，因此对Higgs耦合的偏差非常敏感。我们在HL-LHC和未来的高能量Lepton Colliders中研究了这一过程。我们特别表明，希格斯耦合的场景具有相同的幅度，但相对符号与SM中的相对符号相反，这种场景在没有干扰的情况下很难区分，可以在任何一个对撞机的情况下探测此过程。
We study the production of the Higgs in a association with a vector ($V=W,Z$) via the VBF process, VBF-VH. In the Standard Model (SM), this process exhibits tree-level destructive interference between between $W$ and $Z$ mediated processes and is thus very sensitive to deviations in Higgs couplings to vector bosons. We study this process at both the HL-LHC as well as future high energy lepton colliders. We show in particular that the scenario where Higgs couplings have the same magnitude but opposite relative sign as in the SM, a scenario that is very difficult to distinguish without interference, can be probed with this process at either collider.
