The 2025 International Workshop on the High Energy Circular Electron Positron Collider

The High-Luminosity LHC upgrade will present unprecedented challenges, including intense radiation and up to 200 simultaneous proton collisions. To cope with this, the CMS experiment will deploy a new MIP Timing Detector (MTD) to precisely timestamp MIP particles. This contribution focuses on the MTD's Barrel Timing Layer (BTL), which is now transitioning from a successfully validated design...

Particle identification (PID) plays a crucial role in particle physics experiments. A groundbreaking advancement in PID involves cluster counting (dN/dx), which measures primary ionizations along a particle’s trajectory within a high granularity time projection chamber (TPC), as opposed to conventional dE/dx measurements. A high granularity TPC with a pad size of 0.5x0.5 mm2 has been proposed...

Particle identification (PID) of cosmic‐ray nuclei using silicon strip detectors is employed in many space-born experiments, such as AMS-02, DAMPE, and HERD. However, the detector response exhibits strong dependence on the relative hit position between strips, and the nonlinear effects of front-end electronics under large charges make it difficult to establish explicit analytic expressions for...

This work presents a comprehensive study of charged-hadron particle identification (PID) at the Circular Electron-Positron Collider (CEPC), based on full simulation of hadronic Z-pole events. A unified PID strategy is developed by combining energy loss measurements (dN/dx) from the time projection chamber (TPC) and time-of-flight (ToF) information from both the inner (ITK) and outer (OTK)...
