TLDR
In this article, all the low-energy successes of the standard electroweak gauge model are shown to follow in a more phenomenological model based on global SU(2) broken by γ-W° mixing.Abstract:
All the low-energy successes of the standard electroweak gauge model are shown to follow in a more phenomenological model based on global SU(2) broken by γ-W° mixing. Weinberg’s mass predictions need not be valid. Connections with recent composite models of W and Z are also discussed.read more

Test of compositeness: Zγ processes at the pp TeV colliders
TL;DR: In this paper, light composite spinless weak bosons having technicolour-type coupling to gluon-gluon or a weak universal coupling to fermion pairs were seen at the Tevatron and SSC.
Journal ArticleDOI
Anomalous vector-boson self-interactions
TL;DR: In this paper, the authors study the possibility that vector-boson self-couplings may differ from their standard model values and find that known constraints from loop effects and from unitary already imply that such deviations are of order 10 −2 or less.

Partial Symmetries of Weak Interactions
TL;DR: In this paper, the weak and electromagnetic interactions of leptons are examined under the hypothesis that the weak interactions are mediated by vector bosons, and it is shown that the simplest partially-symmetric model reproducing the observed electromagnetic and weak interactions requires the existence of at least four vector-boson fields (including the photon).

Theory of strong interactions
TL;DR: In this article, a new theory of strong interactions is proposed based on the notion of parity conservation in strong couplings, which is similar to the one proposed in this paper, but with three different types of couplings: hypercharge coupling, isospin coupling, and isobarsin coupling.

Derivation of gauge invariance from high-energy unitarity bounds on the S matrix
TL;DR: In this article, a systematic search is made for all renormalizable theories of heavy vector bosons and it is proved that any such theory is tree-unitary if and only if it is equivalent under a point transformation to a spontaneously broken gauge theory, possibly modified by the addition of mass terms for vectors associated with invariant Abelian subgroups.
