论文摘要
最近有人提出，除了质量$ $ m_h \ sim $ 125 GEV之外，Higgs领域还可以表现出一种新的激发，与$ m^2_h \ sim m^2_h \ sim m^2_h \ ln（λ_s/m_h）$相关的较大质量$ m_h $，其中$λ_s$是$λ_S$是Ultraviolet Cutoff scecter scecter scecter scecter scecter scect。在理论的4D ising极限上执行的传播器的晶格模拟与此两质量图片一致，并导致估计$ M_H \ SIM 700 $ GEV。然而，尽管它的质量很大，但这种较重的状态仍将与低质量状态相同强度的纵向载体玻色子夫妇夫妇，因此将代表相对狭窄的共振。在这封信中，我们认为这种假设的新共鸣自然与某些过量的4-lepton事件相吻合，这是Atlas在680 GEV左右观察到的。
It has been recently proposed that, besides the known resonance with mass $m_h\sim$ 125 GeV, the Higgs field could exhibit a new excitation with a larger mass $M_h$ related by $M^2_h\sim m^2_h \ln (Λ_s/M_h)$, where $Λ_s$ is the ultraviolet cutoff of the scalar sector. Lattice simulations of the propagator performed in the 4D Ising limit of the theory are consistent with this two-mass picture and lead to the estimate $M_h\sim 700$ GeV. In spite of its large mass, however, this heavier state would couple to longitudinal vector bosons with the same typical strength of the low-mass state and would thus represent a relatively narrow resonance. In this Letter we argue that this hypothetical new resonance would naturally fit with some excess of 4-lepton events which is observed by ATLAS around 680 GeV.
