Composite weak bosons in a confining gauge theory without Goldstone bosons: A strong coupling expansion analysis.
We consider a confining Yang-Mills theory without Goldstone Bosons which could describe the bosonic sector of the weak interactions. This model can be gauge invariantly regularized on a lattice. A strong coupling analysis of the low lying bound state spectrum indicates that the vector isotriplet bound state (the right quantum number to represent the W-boson) could be the lightest state if the m...
متن کاملThe imperceptible but inevitable emergence of crises
This short paper argues that economies cannot be simply viewed as the sum of well behaved but isolated individual decision makers. Even if we accept the notion of an equilibrium state, thinking about the economy as a global dynamic system, it may be true that there are several such equilibrium states. It may be the case that small changes in the parameters of the system result in a switch from ...
متن کاملGauge Field Model With Massive Gauge Bosons
[Abstract] A gauge field model, which simultaneously has strict local gauge symmetry and massive gauge bosons, is discussed in this paper. The model has SU(N) gauge symmetry. In the limit α −→ 0, the gauge field model discussed in this paper will return to Yang-Mills gauge field model. The important meaning of this model is that, without Higgs mechanism, gauge bosons can also obtain masses. Thi...
متن کاملPhysics of Electroweak Gauge Bosons
The study of gauge bosons is interesting in two respects. The properties of gauge bosons are modified by higher order effects that are sensitive to mass scales not directly accessible to experiment. On the other hand interactions amongst gauge bosons are sensitive to the symmetry structure of the theory where especially the interactions involving longitudinally polarised bosons teach us about t...
متن کاملLight 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...
