STANDARD MODEL COUPLINGS WITH a'1 = 137 ± 9 FROM MULTIPLE POINT CRITICALITY AND 3 GENERATIONS OF GAUGE BOSONS; NO GUT, NO SUSY

摘要

We consider the application of the Multiple Point Criticality Principle to the Standard Model and its extension to the anti-grand gauge group SMG3 U(l)f at the Planck scale. In particular we discuss the predictions for the fine structure constrants: a~-1(0)=137± 9, a~l{Mz) = 99 ± 5, A_2-1(Mz)=29±6.
