In a recent note' it was shown that the Goldstone theorem, ' that Lorentz-covaria. nt field theories in which spontaneous breakdown of symmetry under an internal Lie group occurs contain zero-mass particles, fails if and only if the conserved currents associated with the internal group are coupled to gauge fields. The purpose of the present note is to report that, as a consequence of this coupling, the spin-one quanta of some of the gauge fields acquire mass; the longitudinal degrees of freedom… Expand
Massive gauge particles versus Goldstone bosons in non-Hermitian non-Abelian gauge theory
We investigate the Englert-Brout-Higgs-Guralnik-Hagen-Kibble mechanism for non-Hermitian field theories with local non-Abelian gauge symmetry in different regions of their parameter spaces. WeExpand
Prehistory of the Higgs boson
A Higgs boson is a particle whose existence is predicted in a class of quantum field theories in which a symmetry under a Lie group of transformations of the fields is spontaneously broken by anExpand
Localization and symmetries
The violation of the Noether relation between symmetries and charges is reduced to the time dependence of the charge associated with a conserved current. For the U(1) gauge symmetry aExpand
Mass Generation Without the Higgs Mechanism
As it is commonly understood, the Higgs mechanism is designed to introduce the masses of the gauge bosons by a spontaneous breaking of the gauge symmetry by an additional field. In this paper weExpand
Topological mass from vortex-electron interaction
We consider the Abelian Higgs model in 3+1 dimensions with vortex lines, into which charged fermions are introduced. This could be viewed as a model of a type-II superconductor with unpairedExpand
Symmetries of Elko and massive vector fields
This thesis studies the symmetries and phenomenologies of the massive vector fields of indefinite spin with both scalar and spin-one degrees of freedom and Elko. The investigation is conducted byExpand
Gauge-invariant microscopic kinetic theory of superconductivity: Application to the optical response of Nambu-Goldstone and Higgs modes
We show that the gauge-invariant kinetic equation of superconductivity provides an efficient approach to study the electromagnetic response of the gapless Nambu-Goldstone and gapful Higgs modes on anExpand
Spontaneously broken gauge theory in strong external fields
Abstract It was proposed in a former paper [A. Schafer, B. Muller and W. Greiner, Phys. Lett. B 149 (1984) 455] that in strong fields the VEV of a Higgs field can become space and time dependent andExpand
Dynamical gauge symmetry breaking in supersymmetry theories
Abstract The supersymmetric extension of the conventional mechanism of dynamical gauge symmetry breaking is presented in the general case where the Goldstone bosons may be either doubled orExpand
Hidden charge-conjugation, parity, and time-reversal symmetries and massive Goldstone (Higgs) modes in superconductors
A massive Goldstone (MG) mode, often referred to as a Higgs amplitude mode, is a collective excitation that arises in a system involving spontaneous breaking of a continuous symmetry, along with aExpand
