Startling Equivalences in the Higgs-goldstone Sector between Radiative and Lowest-order Conventional Electroweak Symmetry Breaking

In the conventional single-Higgs doublet Standard Model Lagrangian, a scalar field mass term within a unification context would necessarily be subject to GUTscale radiative corrections which would require fine-tuning for the Higgs mass to remain within its present indirect-measurement bounds. One of the ways to address this problem is to assume that the electroweak Lagrangian is protected from acquiring such a scalar field mass term by some higher symmetry. The classic Coleman and Weinberg calculation 1 demonstrated that radiative corrections to such a protected Lagrangian would still lead to a spontaneous symmetry breaking in which the Higgs boson mass can be explicitly predicted. However, this calculation preceded
