Over three lectures (2h/day), the course will introduce theoretical and phenomenological aspects of hadron-hadron (day 1), lepton-lepton (day 2), and hadron-lepton (day 3) collider experiments at TeV-scale center-of-mass energies. This includes: an introduction to the Drell-Yan and weak boson scattering processes, an introduction to jets in QCD, muon colliders, neutrino-nucleus deep-inelastic scattering, and factorization in gauge theories.
