AI 中文摘要
粒子鉴别（PID）仍是未来对撞机实验物理计划的关键组成部分。传统对撞机探测器依靠量能器、径迹系统和缪子系统进行粒子分类，而带电强子的鉴别需要通过切伦科夫辐射、电离或飞行时间技术对粒子速度进行专门测量。FCC-ee和电子离子对撞机等未来装置对动量覆盖范围、探测器集成度和材料预算提出了苛刻要求，推动了新型PID概念的发展。本文综述了目前正在研究的几种方法，包括紧凑成像切伦科夫探测器、团簇计数漂移室、增强计时的切伦科夫探测器以及基于先进硅传感器的精密计时系统，还讨论了新兴光电探测器技术的作用以及未来对撞机环境的辐射耐受考量。本文总结了2026年LHCP邀请报告中涉及的主要主题，重点关注选定的代表性示例，而非该领域的全面综述。
英文摘要
Particle identification (PID) remains a key ingredient of the physics programmes of future collider experiments. While traditional collider detectors rely on calorimetry, tracking and muon systems for particle classification, the identification of charged hadrons requires dedicated measurements of particle velocity through Cherenkov radiation, ionisation or time-of-flight techniques. Future facilities such as FCC-ee and the Electron-Ion Collider place demanding requirements on momentum coverage, detector integration and material budget, motivating the development of novel PID concepts. This contribution reviews several approaches currently under investigation, including compact Ring-Imaging Cherenkov detectors, cluster-counting drift chambers, timing-enhanced Cherenkov detectors and precision timing systems based on advanced silicon sensors. The role of emerging photodetector technologies and radiation-tolerance considerations for future collider environments is also discussed. This contribution summarises the main topics presented in the invited LHCP 2026 talk and focuses on selected representative examples rather than a comprehensive review of the field.
