Experimental Methods at High-Energy Colliders

This lecture delves into the experimental methods used at high-energy colliders, focusing on the CMS detector at CERN's LHC. It covers the components of the detector, such as silicon trackers, muon chambers, and calorimeters, as well as the reconstruction goals for stable particles and jets. The lecture also explores the inner tracking systems, track finding algorithms, vertex reconstruction, and the challenges faced in tracking performance. It discusses the detection of particles not interacting with the detector, missing transverse momentum, and the reconstruction of taus. The presentation concludes with an overview of the achievements in particle reconstruction and the future challenges in the field.
