dc.description.abstract | The recent confirmation of the muon g- 2 anomaly by the Fermilab g- 2 experiment may harbinger a new era in μ and τ physics. In the context of general two Higgs doublet model, the discrepancy can be explained via one-loop exchange of sub-TeV exotic scalar and pseudoscalars, namely H and A, that have flavor changing neutral couplings ρτμ and ρμτ at ? 20 times the usual tau Yukawa coupling, λτ. Taking ρ??′?λmin(?,?′), we show that the above solution to muon g- 2 then predicts enhanced rates of various charged lepton flavor violating processes, which should be accessible at upcoming experiments. We cover muon related processes such as μ→ eγ, μ→ eee and μN→ eN, and τ decays τ→ μγ and τ→ μμμ. A similar one-loop diagram with ρeτ= ρτe= O(λe) induces μ→ eγ, bringing the rate right into the sensitivity of the MEG?II experiment. The μeγ dipole can be probed further by μ→ 3 e and μN→ eN. With its promised sensitivity range and ability to use different nuclei, the μN→ eN conversion experiments can not only make discovery, but access the extra diagonal quark Yukawa couplings ρqq. For the τ lepton, we find that τ→ μγ would probe ρττ down to λτ or lower, while τ→ 3 μ would probe ρμμ to O(λμ). ? 2021, The Author(s). | - |
