Description

In this talk I will discuss the physics potential of high-energy lepton colliders, taking a muon collider in the multi-TeV center-of-mass energy as a template. I will discuss the key differences and similarities with respect to low-energy e+e- machines, e.g. LEP or future e+e- FCC/CEPC/ILC, as well as the differences and similarities with respect to the hadron machines. I will highlight the increasingly important role of weak radiation as new theme in SM physics and collider phenomenology for this new kind of machines and will also assess its importance for searches of BSM physics, e.g. Higgs boson compositeness, WIMP dark matter, etc. Finally I will draft a list of physics items on which progress is needed for our advancement of understanding the SM and fundamental interactions and how colliders, and especially a multi-TeV muon collider, can provide crucial inputs to progress our understanding of Nature.
