Description
The recent discovery of the Higgs boson has been a triumph of the LHC. However, a lepton collider would produce the Higgs boson alone in the final state and would allow studying its couplings and any new physics appearing in the production process better than at the LHC.
A number of future multi-TeV lepton colliders are being actively considered, but the best option is still to be determined. It could be a linear electron-positron collider, an enlarged version of LEP2, but also a Muon Collider.
Since muons loose much less energy for synchrotron radiation when accelerated in a ring, a circular muon collider would have a much smaller size than a circular electron collider of the same energy. However, technological challenges facing the realization of a Muon Collider are very serious. Muons must be produced, accelerated and collided quickly before they decay. This requires developing new techniques of acceleration and cooling.
The muon accelerator program (MAP) is considering the concept of a muon collider that would fit into the Fermilab site. A necessary step towards the realization of this project is the MICE experiment, hosted at RAL, which must give an experimental proof of an innovative cooling technique named “ionization cooling”.
The Fermilab MAP project is involved in the realization and testing of many components of MICE. The speaker has taken part in this effort by testing and tuning a prototype 201 MHz RF cavity to be installed on MICE.
A survey of the main parameters of a muon collider will be presented and the MAP concept will be described in some detail.
A view of MICE and of the on-going activities at FNAL will also be given.
The speaker will express his personal view on the status of the project, in an attempt to understand if, how and when we could ever see the realization of a Muon Collider.
