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…
Neutral-kaon decays can show CP violation through experimental efficiency
—
What the study found CP violation in the kaon system can appear in decays to final states that contain neutral kaons. The authors say the relevant efficiency can be split into a kaon-energy part and a detector-dependent part that does not depend on the decay process. Why the authors say this matters The study suggests…
2HDM-I can explain 650 GeV and 95 GeV anomalies
What the study found The authors report that the 2-Higgs Doublet Model Type-I (2HDM-I), a theory with two Higgs boson fields and a softly broken symmetry, can explain the reported 650 GeV and 95 GeV anomalies. Why the authors say this matters The study suggests that these anomalies, seen in Large Hadron Collider (LHC) and…
