If scale invariance is exact, unparticles are unlikely to be probed in colliders since there are stringent constraints from astrophysics and cosmology. However these constraints are inapplicable if scale invariance is broken at a scale mu >~ 1 GeV. The case 1 GeV mu+ mu- cross-section and forward-backward asymmetry data, and compare with the constraints from mono-photon production and the Z hadronic width.
