Description
A multi-TeV muon collider is one of the best candidates under investigation for the future development of high energy particle physics. Since the discovery of the Higgs boson at the LHC in 2012, a great effort has been made in order to probe its properties. Nevertheless, almost all the Higgs boson couplings to second and third generation fermions and self couplings are still out of reach and, unfortunately, will not be completely accessed even at the High Luminosity era of LHC (HL-LHC). For this reason, one of the main goals future colliders have to accomplish is the measurement of the Higgs boson couplings with a precision of a few percent.
A 14 TeV muon collider with sufficient luminosity would provide a similar discovery reach as a 100 TeV hadron collider. Moreover, a muon collider would lose much less synchrotron radiation than an analogous electron-positron machine.
At a multi-TeV muon collider, the vector boson fusion/scattering would be the dominant production mechanism, allowing us to study with high precision all the Standard Model processes and, if possible, probe for new physics. With sufficient luminosity, it would also be possible to directly measure the Higgs boson trilinear and quadrilinear self-couplings, necessary to determine the Higgs potential.
In order to investigate the physics potential of such a facility, the International Muon Collider Collaboration (IMCC) has developed a framework to perform detailed simulations of the physics processes of interest, which include a realistic detector response. This work will give an overview of a selected set of results, focusing on the Higgs boson couplings.
