Radiative Corrections as the Origin of Spontaneous Symmetry Breaking

  title={Radiative Corrections as the Origin of Spontaneous Symmetry Breaking},
  author={E. Weinberg},
  journal={Physical Review D},
We investigate the possibility that radiative corrections may produce spontaneous symmetry breakdown in theories for which the semiclassical (tree) approximation does not indicate such breakdown. The simplest model in which this phenomenon occurs is the electrodynamics of massless scalar mesons. We find (for small coupling constants) that this theory more closely resembles the theory with an imaginary mass (the Abelian Higgs model) than one with a positive mass; spontaneous symmetry breaking… Expand

Quantum radiative corrections to slow-roll inflation
We consider the nonminimally coupled {lambda}{phi}{sup 4} scalar field theory in de Sitter space and construct the renormalization group improved renormalized effective theory at the one-loop level.Expand
Electroweak baryogenesis with a pseudo-Goldstone Higgs boson
We examine the nature of electroweak Baryogenesis when the Higgs boson's properties are modified by the effects of new physics. We utilize the effective potential to one loop (ring improving theExpand
Phase of confined electroweak force in the early Universe
We consider a modified cosmological history in which the presence of beyond-the-Standard-Model physics causes the weak gauge sector, $\mathrm{SU}(2)_L$, to confine before it is Higgsed. Under theExpand
Two-loop stability of a complex singlet extended Standard Model
Motivated by the dark matter and the baryon asymmetry problems, we analyze a complex singlet extension of the Standard Model with a ${\mathbb{Z}}_{2}$ symmetry (which provides a dark matterExpand
Spontaneous symmetry breaking in the linear sigma model at finite chemical potential: One-loop corrections
We investigate spontaneous symmetry breaking within the linear sigma model with the $\mathrm{SU}(2)\ifmmode\times\else\texttimes\fi{}\mathrm{U}(1)$ internal symmetry at finite chemical potential,Expand
Rotation symmetry breaking condensate in a scalar theory
Motivated by an analogy with the conformal factor problem in gravitational theories of the $R+R^2$-type we investigate a $d$-dimensional Euclidean field theory containing a complex scalar field withExpand
Protecting the stability of the electroweak vacuum from Planck-scale gravitational effects
We investigate the stability of the Standard-Model Electroweak (EW) vacuum in the presence of Planck-scale suppressed operators of the type $\phi^{2n}/M^{2n-4}_{\rm P}$ that involve the Higgs fieldExpand
Variational technique for gauge boson masses
In this work, a novel mechanism for spontaneous symmetry breaking is presented. This mechanism incorporates gravity in the generation of masses for gauge fields, showing that the Higgs mechanism canExpand
In this paper we investigate the phase transition "Coulomb-confinement" in the Higgs model of Abelian scalar dyons – particles having both, electric e and magnetic g, charges. It is shown that byExpand
Theoretical constraints on the Higgs effective couplings
We derive constraints on the sign of couplings in an effective Higgs Lagrangian using prime principles such as the naturalness principle, global symmetries, and unitarity. Specifically, we study fourExpand
