New precision timing capabilities for the ATLAS experiment at HL-LHC

Host: Toyoko Orimoto

 

The High-Luminosity Large Hadron Collider is scheduled to start colliding protons in 2026 and will deliver approximately 20 times more data than the LHC has produced to date. This will both enable higher-precision measurements of several Standard Model processes (e.g. involving the Higgs) and offer improved sensitivity for searches for new particles and processes. The increased interaction rate creates a harsh environment for the detectors that will need to be able to discern up to 200 pp collisions in a volume the size of a human hair. A novel way to disentangle interesting physics processes from the pileup interactions is to use picosecond timing measurements. The ATLAS experiment will be equipped with the High-Granularity Timing Detector based on recently developed silicon technology which provides this capability. I will present an overview of this project, from the design considerations of the detector to the expected impact on the physics performance of the experiment.
