- noun Plural form of
Sorry, no etymologies found.
To achieve different symmetries in the neutrino and charged lepton sectors we need to align the Higgs fields which break the family symmetry (called flavons) along different symmetry-preserving directions (called vacuum alignment).
If TMB is accurately realized, this may imply a new symmetry of nature: a family symmetry, broken by flavons.
We need to have a triplet of flavons which breaks the A4 symmetry.
These models are economical, they involve only two flavons.
