论文摘要
我们考虑了标准模型的扩展，其中有两个右手的单线费尔米斯，其质量在伊莱克克量表上引起中微子质量，再加上一个通用的新物理部门，较高级别$λ$。我们专注于最低尺寸的有效运营商$ d = 5 $，这会引起新的生产和衰减模式。我们评估未来HIGGS工厂的敏感性，例如FCC-EE，CLIC-380，ILC和CEPC，对这些操作员在各种质量能量中心的系数。我们表明，未来的Lepton Colliders可以测试该理论的截止值，最高可达$λ\ simeq 500-1000 \; $ tev，超过了Higgs和$ Z $ Boson宽度的未来间接测量。我们还评论如果观察到新的物理信号，以及更高维$ d = 6 $ operators对实验签名的影响，则可以确定基本模型的风味结构。
We consider an extension of the Standard Model with two right-handed singlet fermions with mass at the electroweak scale that induce neutrino masses, plus a generic new physics sector at a higher scale $Λ$. We focus on the effective operators of lowest dimension $d=5$, which induce new production and decay modes for the singlet fermions. We assess the sensitivity of future Higgs Factories, such as FCC-ee, CLIC-380, ILC and CEPC, to the coefficients of these operators for various center of mass energies. We show that future lepton colliders can test the cut-off of the theory up to $Λ\simeq 500 - 1000\;$TeV, surpassing the reach of future indirect measurements of the Higgs and $Z$ boson widths. We also comment on the possibility of determining the underlying model flavor structure should a New Physics signal be observed, and on the impact of higher dimensional $d=6$ operators on the experimental signatures.
