High-energy muon colliders have significant potential for exploring core themes such as electroweak symmetry breaking, naturalness, and dark matter, which have shaped the quest for new physics since the inception of the Standard Model. The recent discovery of the Higgs reveals both its central role in the Standard Model and many unresolved puzzles regarding the Higgs field. Electroweak symmetry breaking is crucial for understanding elementary particle masses, yet many model parameters require further measurement, indicating that multiple collider experiments may be necessary to uncover all aspects of the Standard Model fully.
The discovery of the Higgs completed the particle content of the Standard Model but has deepened the puzzles regarding the Higgs field's role, prompting a need for further measurements.
Electroweak symmetry breaking is integral to the Standard Model as it's responsible for the masses of elementary particles. However, much remains unresolved about the Higgs parameters.
Future high-energy muon colliders should focus on key physics themes such as electroweak symmetry breaking, naturalness, and dark matter to explore the foundations of the Standard Model.
The Higgs is not uniquely determined by gauge invariance, necessitating precise measurements of its parameters, and raises questions about the completion of the Standard Model.
