A4 symmetry gives best match in leptonic 3HDM
What the study found The study found that, in the three-Higgs-doublet model, assigning the Higgs doublets to transform as a flavor triplet under the A4 group reproduces the experimentally observed neutrino mixing angles with arbitrary precision. It also keeps the correct mass ordering for charged leptons and for neutral leptons, which are Dirac neutrinos with…
