论文摘要
预计下一代循环高能对撞机将是一名轻顿对撞机，在中国CERN或CEPC的FCC-EE。但是，土木工程概念预见到这些对船员的探测器洞穴的装备要比Lepton Collider需要的更大，因此可以将它们用于可以在不进一步的土木工程的情况下安装在同一隧道中的强子对撞机。这打开了在洞穴墙壁上安装额外仪器的可能性，以在Lepton Collider上寻找新的长寿命颗粒。我们以重中性瘦素的示例表明，这种安装可以提高对平方混合参数的敏感性几乎一半的数量级。
The next generation of circular high energy collider is expected to be a lepton collider, FCC-ee at CERN or CEPC in China. However, the civil engineering concepts foresee to equip these colliders with bigger detector caverns than one would need for a lepton collider, so that they can be used for a hadron collider that may be installed in the same tunnel without further civil engineering. This opens up the possibility to install extra instrumentation at the cavern walls to search for new long-lived particles at the lepton collider. We use the example of heavy neutral leptons to show that such an installation could improve the sensitivity to the squared mixing parameter by almost half an order of magnitude.
