论文摘要
我们探索了$ {pp \ to H^* \ rightArrow Z（\ ell^{+} \ ell^{ - }）z（n^{ - }）z（ν\barν）} $通道的新物理范围。新的物理敏感性是根据希格斯玻色子宽度，有效的现场理论框架和非本地希格斯 - 顶式耦合形式的。采用机器学习技术，我们证明了由于横向$ ZZ $质量的较大信号速率和过程能量量表的精确现象学探针的组合，从而超出了考虑新物理场景的文献中现有结果的显着敏感性。
We explore the new physics reach for the off-shell Higgs boson measurement in the ${pp \to H^* \rightarrow Z(\ell^{+}\ell^{-})Z(ν\barν)}$ channel at the high-luminosity LHC. The new physics sensitivity is parametrized in terms of the Higgs boson width, effective field theory framework, and a non-local Higgs-top coupling form factor. Adopting Machine-learning techniques, we demonstrate that the combination of a large signal rate and a precise phenomenological probe for the process energy scale, due to the transverse $ZZ$ mass, leads to significant sensitivities beyond the existing results in the literature for the new physics scenarios considered.
