The gauge unparticles ('ungluons')

摘要

A field model for a quark and an antiquark binding is described. Quarks interact via a gauge unparticle ("ungluon"). The model is formulated in terms of Lagrangian which features the source field S(x) which becomes a local pseudo-Goldstone field of conformal symmetry - the pseudodilaton mode and from which the gauge non-primary unparticle field is derived by B_μ(x) ~ ?_μS(x). Because the conformal sector is strongly coupled, the mode S(x) may be one of new states accessible at high energies. We have carried out an analysis of the important quantity that enters in the "ungluon" exchange pattern - the "ungluon" propagator.
