Description

Various possibilities for testing lepton dipole moments in high-energy collider experiments are investigated. A Muon Collider running at center-of-mass energies of several TeV could provide the first model-independent high-energy test of new physics in the muon g-2, being sensitive to deviations of few $\times\, 10^{-9}$, thus being able to shed light on the long-standing muon g-2 anomaly. At the same time, the current bound on the muon electric dipole moment can be improved by three orders of magnitude, down to few $\times\, 10^{-22}\, e$ cm. Stringent constraints on the tau dipole moment can instead be obtained from various high-energy processes (such as Drell-Yan, VBF, or tau production in association with a Higgs boson), or from precision measurements of rare Higgs decay modes.
