论文摘要
未来的圆形对撞机（FCC-HH）是大型强子对撞机（LHC）的拟议继任者。 FCC-HH会推动对新物理颗粒进行搜索的能量和强度边界。特别是，由于LHC的能量和发光度更高，在FCC-HH上，将生产出$ \ simeq \！30美元$倍的$ b $ emons和$ \ simeq 120 $ w $ bosons，然后可能会腐烂成易于相互作用的粒子。在本文中，我们通过研究其对重型中性瘦素（HNLS）的敏感性来证明FCC-HH的潜力。我们考虑了嵌入在FCC-HH计划的基础设施中的流离失所衰减体积的各个位置。我们证明，与LHC提出的搜索相比，FCC-HH可以显着改善HNLS参数空间的覆盖范围。
The Future Circular Collider (FCC-hh) is a proposed successor of the Large Hadron Collider (LHC). FCC-hh would push both the energy and intensity frontiers of searches for new physics particles. In particular, due to higher energy and luminosity than at the LHC, at FCC-hh there would be produced around $\simeq\!30$ times larger amount of $B$ mesons and $\simeq 120$ times of $W$ bosons, which then may decay into feebly interacting particles. In this paper we demonstrate the potential of FCC-hh by studying its sensitivity to heavy neutral leptons (HNLs) with masses $m_{N}<m_{B}$. We consider various locations of a displaced decay volume embedded in the planned infrastructure of FCC-hh. We demonstrate that FCC-hh may substantially improve the reach of the parameter space of HNLs as compared to the searches proposed at the LHC.
