Theory of electroweak interactions without spontaneous symmetry breaking [PDF]
arXiv, 1999 The study of a EW theory without spontaneous symmetry breaking is presented. A new symmetry breaking, axial-vector symmetry breaking, is found. M^{2}_{W}=1/2g^{2}m^{2}_{t}, m^{2}_{Z}=\rho m^{2}_{W}/cos^{2} \theta, and G_{F}=1/(2\sqrt{2}m^{2}_{t}) are obtained and they agree with data. It has been proved that the theory is renormalizable and unitary.

Gravity Theories with Background Fields and Spacetime Symmetry Breaking
, 2017 An overview is given of effective gravitational field theories with fixed background fields that break spacetime symmetry. The behavior of the background fields and the types of excitations that can occur depend on whether the symmetry breaking is ...

Fluctuation operators and spontaneous symmetry breaking [PDF]
Journal of Mathematical Physics, 2002 We develop an alternative approach to this field, which was to a large extent developed by Verbeure et al. It is meant to complement their approach, which is largely based on a noncommutative central limit theorem and coordinate space estimates. In contrast to that we deal directly with the limits of l-point truncated correlation functions and show ...

BMS supertranslation symmetry implies Faddeev-Kulish amplitudes
Journal of High Energy Physics, 2018 We show explicitly that, among the scattering amplitudes constructed from eigenstates of the BMS supertranslation charge, the ones that conserve this charge, are equal to those constructed from Faddeev-Kulish states. Thus, Faddeev-Kulish states naturally

The classification of corank one forced symmetry breaking [PDF]
, 2007 Forced-symmetry breaking occurs when a bifurcation equation changes its symmetry when a parameter varies. It is to be contrasted with the phenomena of spontaneous symmetry breaking when the symmetry of the equations are kept constant but the symmetry of

Modified spontaneous symmetry breaking pattern by brane-bulk interaction terms
, 2007 We show how translational invariance can be broken by the vacuum that drives the spontaneous symmetry breaking of extra-dimensional extensions of the Standard Model, when delta-like interactions between brane and bulk scalar fields are present.

Re-Interpretation of Spontaneous Symmetry Breaking in Quantum Field Theory and Goldstone Theorem [PDF]
arXiv, 2005 We present a new picture of global symmetry breaking in quantum field theory and propose a novel realization of symmetry breaking phenomena in terms of the conserved charge associated with its symmetry. In particular, the fermion condensate of the vacuum state is examined when the spontaneous chiral symmetry breaking takes place.
