论文摘要
具有超快速计时（10-30 PS）和非常精细的空间分辨率（O（几$ $ $ m））的4维（4D）跟踪器代表了开发硅跟踪器的新途径，从而使新的物理学能力超出了现有跟踪探测器的范围。本文回顾了在HL-LHC实验的潜在升级和未来颜色的几个探测器中整合4D跟踪能力对几种物理基准的影响，并总结了当前可用的传感器技术以及电子设备，以及它们的限制和方向。
4-dimensional (4D) trackers with ultra fast timing (10-30 ps) and very fine spatial resolution (O(few $μ$m)) represent a new avenue in the development of silicon trackers, enabling new physics capabilities beyond the reach of the existing tracking detectors. This paper reviews the impact of integrating 4D tracking capabilities on several physics benchmarks both in potential upgrades of the HL-LHC experiments and in several detectors at future colliders, and summarizes the currently available sensor technologies as well as electronics, along with their limitations and directions for R$\&$D.
