Flipped SU(5)

The Flipped SU(5) model is a grand unified theory (GUT) first contemplated by Stephen Barr in 1982,[1] and by Dimitri Nanopoulos and others in 1984.[2][3] Ignatios Antoniadis, John Ellis, John Hagelin, and Dimitri Nanopoulos developed the supersymmetric flipped SU(5), derived from the deeper-level superstring.[4][5]

In 2010, efforts to explain the theoretical underpinnings for observed neutrino masses were being developed in the context of supersymmetric flipped SU(5).[6]

Flipped SU(5) is not a fully unified model, because the U(1)Y factor of the Standard Model gauge group is within the U(1) factor of the GUT group. The addition of states below Mx in this model, while solving certain threshold correction issues in string theory, makes the model merely descriptive, rather than predictive.[7]
