MuCol: a new Muon Collider initiative for Europe

by Natalia Milas (ESS)


Muon colliders have a great potential for high-energy physics. They can offer clean collisions of particles at very high energies, since muons can be accelerated in rings with almost no limitation from synchrotron radiation. However, the need for high luminosity brings technical challenges which arise from the short muon lifetime at rest and the difficulty of producing large numbers of muons in bunches with small emittance. Addressing these challenges requires the development of innovative concepts and demanding technologies. In 2021, an International Muon Collider Collaboration was initiated and from that several laboratories in EU, including ESS and Uppsala, joined efforts in submitting a grant for a design study that was recently approved.
This talk will go through the main aspects of a Muon Collider facility, will summarize the progress achieved and new recent ideas on muon colliders and outline further studies and actions needed to advance in the field.
