MUonE, muon $g - 2$ and electroweak precision constraints within 2HDMs

Oliver Atkinson, Matthew Black, Christoph Englert +2

Two Higgs doublet models are attractive scenarios for physics beyond the Standard Model. In particular, lepton-specific manifestations remain contenders to explain the observed dis…
