Description:

The Higgs boson successfully describes the symmetry breaking mechanism that splits the electromagnetic and the weak nuclear forces apart. In order to understand the microscopic theory behind the Higgs mechanism we need to put the Higgs under a “microscope.” The muon collider will be able to measure the couplings of the Higgs at the 0.1% level, in with this, shed light into this mystery of nature. This machine will also allow us to reach a new energy frontier and to test the Standard Model in new ways. At very high energies a muon beam is expected to behave like an electroweak parton beam (in a similar way how a proton beam is a colored parton beam). In this regime, one will be able to measure the neutrino content of the muon beam, and to test the notion of electroweak symmetry restoration. Finally,  Dark Matter is one of the main motivations for physics beyond the Standard Model. The WIMP miracle is an appealing theory for DM. If Minimal WIMP model particles exist, and they provide either 100% or a fraction of the DM in the Universe, we will discover them at the muon collider.
