论文摘要
在接下来的十年中，强度边界实验将需要跟踪系统，这些系统在保持出色的跟踪性能的同时，在高事件和背景速度上具有强大的影响。我们为假设未来的实验开发了第一个概念设计，这是一个围绕时间投影室（TPC）的Belle II构建的继任者，并具有高分辨率读数。这种选择需要大量扩展硅顶点探测器以及新的快速正时层。我们在Belle II仿真框架中模拟了此类系统的性能，探究其主要技术挑战，并证明这种系统适合下一代强度 - 弗朗西特山脉的投影灯泡。
In the next decade, intensity frontier experiments will require tracking systems that are robust against high event and background rates while maintaining excellent tracking performance. We develop a first conceptual design of a tracking system for a hypothetical future experiment--here imagined as a successor to Belle II--built around a time projection chamber (TPC) with high resolution readout. This choice necessitates a significant expansion of the silicon vertex detector as well as a new fast timing layer. We simulate the performance of such a system in the Belle II simulation framework, probe its major technical challenges, and demonstrate that such a system is suitable for projected luminosities at the next generation of intensity-frontier colliders.
