Intermediate Vector Bosons

Solitonic Photons and Intermediate Vector Bosons

A four-dimensional topological field theory is introduced which generalises B ∧ F theory to give a Bogomol'nyi structure. A class of non-singular, finite-Action, stable solutions to the variational field equations is identified. The solitonic solutions are analogous to the instanton in Yang-Mills theory. The solutions to the Bogomol'nyi equations in the topologically least complicated U (1) the...

Light composite vector bosons.

In gauge theories with slowly-running coupling constants, it may be possible for four-fermion operators to be nearly marginal. Such operators can possess asymptotically weak couplings, and can plausibly give rise to light composite vector mesons. † On leave from the Centre d’Etudes de Saclay, F-91191 Gif-sur-Yvette cedex, France CERN-TH.6767/92 December, 1992 The so-called Standard Model of acc...

Chameleon Vector Bosons

We show that for a force mediated by a vector particle coupled to a conserved U(1) charge, the apparent range and strength can depend on the size and density of the source, and the proximity to other sources. This “chameleon” effect is due to screening from a light charged scalar. Such screening can weaken astrophysical constraints on new gauge bosons. As an example we consider the constraints ...

Coulomb problem for vector bosons

The Coulomb problem for vector bosons W incorporates a well known difficulty; the charge of the boson localized in a close vicinity of the attractive Coulomb center proves be infinite. This fact contradicts the renormalizability of the Standard Model, which presumes that at small distances all physical quantities are well defined. The paradox is shown to be resolved by the QED vacuum polarizati...
