标题： Accuracy complements energy: electroweak precision tests at Tera-Z

摘要： 一个Tera-$Z$工厂，如FCC-ee或CEPC，将通过在$Z$极点处的高阶环贡献对重新物理具有间接灵敏度，可达数十TeV尺度。 这些间接量子效应可能提供补充，甚至更好的灵敏度，以探测通常认为在高于$Z$极点的较高能量下最好被约束的规范模型偏差。 我们在SMEFT框架中展示了精度如何补充能量，对于修改希格斯和规范玻色子二点和三点函数的算符，导致对如实单态标量、弱相互作用大质量粒子和守恒弱四重态模型的改进预测灵敏度。 一个全面的 Tera-$Z$计划可能会预见更高能量物理运行的某些方面，并提供比以前所认识到的更广泛的TeV尺度量子探索范围。 显示英文摘要

摘要： A Tera-$Z$ factory, such as FCC-ee or CEPC, will have indirect sensitivity to heavy new physics up to the tens of TeV scale through higher-order loop contributions to precision measurements at the $Z$ pole. These indirect quantum effects may provide complementary, or even better, sensitivity to potential deviations from the Standard Model that are typically thought to best be constrained at leading order at higher energies above the $Z$ pole. We show in the SMEFT framework how accuracy complements energy for operators that modify the Higgs and gauge boson two- and three-point functions, leading to improved projected sensitivities for models such as the real singlet scalar, weakly interacting massive particles, and a custodial weak quadruplet. A thorough Tera-$Z$ programme may thus anticipate aspects of physics runs at higher energies and provide a wider scope of quantum exploration of the TeV scale than had previously been appreciated.
