Flipped SU(5) - The Model

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)
