Bifurcations & the Gauge Structure of the Standard Model

Abstract

As of today, the reason for the unique composition of the Standard Model (SM) gauge group SU(3)_c x SU(2)_l x U(1) remains elusive. Taking complex-scalar field theory as baseline model, we argue here that the SM group unfolds sequentially from bifurcations driven by the Renormalization scale. Numerical estimates are found to be reasonably consistent with experimental data.
