Next generation tracking and vertexing detectors
Abstract
Precise and efficient track and vertex reconstruction is essential to exploit the physics potential of collider experiments. The requirements of future tracking systems are determined by the collider type and its collision environment, required measurement precision, and beam structure. This contribution reviews the requirements and challenges of vertexing and tracking detectors at future e+e-, e--hadron, μ+μ-, and hadron colliders. Several common trends emerge across the different collider types. Tracking systems require increasingly precise spatial measurements, low-material designs, and, in some cases, integrated particle identification capabilities. Monolithic active pixel sensors are currently the leading option for vertex detectors at e+e- and e--hadron colliders. Tracker concepts range from gaseous detectors, which provide many measurements per track and can achieve very low material budgets, to silicon and scintillating-fibre trackers, which provide fewer but more precise measurements and can tolerate higher hit rates. At 10 TeV parton centre-of-mass colliders, precision timing throughout the tracking system is needed for beam-background rejection or pile-up mitigation. For future hadron colliders specifically, radiation tolerance beyond that demonstrated by existing sensor technologies is required. Ultimately, meeting the vertexing and tracking requirements of future colliders will require substantial R&D and the integrated optimisation of sensors, front-end electronics, readout, cooling, powering, and mechanics.

The requirements of future tracking systems are determined by the collider type and its collision environment, required measurement precision, and beam structure. This contribution reviews the requirements and challenges of vertexing and tracking detectors at future e^+e^-, e^--hadron, μ^+μ^-, and hadron colliders.
