Abstract
Charged-lepton flavour-violating (cLFV) processes o er deep probes for new physics with discovery
sensitivity to a broad array of new physics models | SUSY, Higgs Doublets, Extra Dimensions, and, particularly, models explaining the neutrino mass hierarchy and the matter-antimatter asymmetry of the universe via leptogenesis. The most sensitive probes of cLFV utilize high-intensity muon beams to search for μ → e transitions.
We summarize the status of muon-cLFV experiments currently under construction at PSI, Fermilab,
and J-PARC. These experiments o er sensitivity to e ective new physics mass scales approaching 𝒪(10^4) TeV/c^2. Further improvements are possible and next-generation experiments,
using upgraded accelerator facilities at PSI, Fermilab, and J-PARC, could begin data
taking within the next decade. In the case of discoveries at the LHC, they could distinguish
among alternative models; even in the absence of direct discoveries, they could establish new
physics. These experiments both complement and extend the searches at the LHC.
