The Model
The Flipped SU(5) model states that the gauge group is:
Fermions form three families, each consisting of the representations
This assignment includes three right-handed neutrinos, which have never been observed, but are often postulated to explain the lightness of the observed neutrinos and neutrino oscillations. There is also a and/or called the Higgs fields which acquire a VEV, yielding the spontaneous symmetry breaking
The SU(5) representations transform under this subgroup as the reducible representation as follows:
- (uc and l)
- (q, dc and νc)
- (ec)
- .

“The playing adult steps sideward into another reality; the playing child advances forward to new stages of mastery....Childs play is the infantile form of the human ability to deal with experience by creating model situations and to master reality by experiment and planning.”
—Erik H. Erikson (20th century)
