论文摘要
可以在Dilepton频道$ h \ to ww \ to ww \ to \ellν\ ellν$中使用实验室框架可观察到仅涉及带电的leptons $ \ ell Ell \ ell = e，μ$ $ $ $ $ $ $ higgs玻色子衰减产生的两个$ w $玻色子之间的量子纠缠。 DILEPTON不变质量分布已经通过LHC的Atlas和CMS合作来衡量，可用于观察$ WW $对的量子纠缠，其统计灵敏度为$7σ$，具有2美元的统计灵敏度，并且在包括理论系统的包括$6σ$中。作为副产品，写下了$ W $ REST框架（四维）角度分布之间的关系，$ h \ to WW $衰减振幅和自旋相关系数。
Quantum entanglement between the two $W$ bosons resulting from the decay of a Higgs boson may be investigated in the dilepton channel $H \to WW \to \ell ν\ell ν$ using laboratory-frame observables that only involve the charged leptons $\ell=e,μ$. The dilepton invariant mass distribution, already measured by the ATLAS and CMS Collaborations at the LHC, can be used to observe the quantum entanglement of the $WW$ pair with a statistical sensitivity of $7σ$ with Run 2 data, and of $6σ$ when including theoretical systematics. As a by-product, the relation between $W$ rest frame (four-dimensional) angular distributions, $H \to WW$ decay amplitudes, and spin correlation coefficients, is written down.
