Standard Model Couplings with ${\alpha }^{-1}=137\pm 9$ from Multiple Point Criticality and 3 Generations of Gauge Bosons: No GUT, No SUSY

D. L. Bennett, C. D. Froggatt, H. B. Nielsen

We consider the application of the Multiple Point Criticality Principle to the Standard Model and its extension to the anti-grand gauge group $SM{G}^3\otimes U(1{)}_f$ at the Planck s…
