“…Although potential operational scenarios are still under active discussion, the inclusive Higgs production at an O(10) TeV muon collider with O(100 ab −1 ) of data would yield O(10 8 ) Higgs bosons, two orders of magnitude larger than the production at proposed e + e − Higgs factories. In addition, given the low-background environment at a muon collider, such machines can provide an excellent opportunity to investigate exotic Higgs decays beyond the reach of the HL-LHC, offering sensitivity to ultra-rare exotic decay modes with branching fractions down to O(10 −7 ) [145,146].…”

Exotic decays of the Standard Model-like Higgs boson into beyond-the-Standard Model particles are predicted in a wide range of well-motivated theories. The enormous samples of Higgs bosons that have been and will be produced at the Large Hadron Collider thus constitute one of the key discovery opportunities at that facility, particularly in the upcoming high-statistics high-luminosity run. Here we review recent theoretical work on models that predict or accommodate exotic Higgs decays, the status of current experimental searches, and look forward to future capabilities at dedicated Higgs factories and beyond.

“…We focus on the anomalous W W γ coupling in the photon-induced process at the multi-TeV muon collider. In order to specify the most suitable muon collider, we consider various center-of-mass energies from 3 to 100 TeV and integrated luminosities increasing in proportion to [19] L int = 10 ab −1 √ s 10 TeV…”

The pursuit of discovery in particle physics has always required study at the highest possible energies. Multi-TeV muon colliders, which have important advantages, offer unprecedented potential for investigating new physics beyond the Standard Model. We extensively assume a range of center-of-mass energies from 3 to 100 TeV and a range of integrated luminosities from 1 to 1000 ab −1 for future multi-TeV muon colliders. We perform a phenomenological study of the anomalous W W γ couplings via the process µ + µ − → µ + γ * µ − → µ + W − ν µ using a model-independent analysis in the effective field theory framework at multi-TeV muon colliders. All signal events in the existence of anomalous c W W W /Λ 2 , c W /Λ 2 and c B /Λ 2 couplings and the relevant background events are calculated in MadGraph. The sensitivity estimates obtained for the anomalous W W γ couplings at systematic uncertainties of δ sys = 0, 3, 5% are compared with the experimental results.Our best sensitivity limits at 95% confidence level for c W W W /Λ 2 , c W /Λ 2 and c B /Λ 2 couplings are [−0.0000329; 0.0000241] TeV −2 , [−0.025594; 0.029431] TeV −2 and [−0.025634; 0.029427] TeV −2 at the multi-TeV muon collider with center-of-mass energy of 100 TeV and integrated luminosity of 1000 ab −1 , respectively.

The investigation of the energy frontier in physics requires novel concept for future colliders. The idea of a muon collider is very appealing since it would aim to study particle collisions up to tens of TeV energy while offering a cleaner experimental environment with respect to hadronic colliders. One key element in the muon collider design is muon production with small emittance. Recently, the Low EMittance Muon Accelerator (LEMMA) collaboration has explored the close-to-threshold muon production by 45 GeV positron annihilating in a low Z material target. Muons are emerging with a natural small emittance. In this
