The models in the two papers hep-ph/0608068 and hep-ph/0701254 by Chang et al. with the so-called shadow gauge and scalar fields are nothing but convenient tailored versions of our model in hep-th/0403039. The same remarks applies to the work in hep-th/0612165 by Meissner and Nicolai.

Comment on Electroweak Higgs as a Pseudo-Goldstone Boson of Broken Scale Invariance

The first model of Foot, Kobakhidze and Volkas described in their work in arXiv:0704.1165 [hep-ph] is a tailored version of our model on broken scale invariance in the standard model presented in…

Comment on Papers by Foot, Kobakhidze, McDonald and Volkas Relating to Scale Invariance Symmetry

We point out that the works described by Foot et al. in arXiv:0706.1829 [hep-ph] and arXiv:0709.2750 [hep-ph] are derivatives of our work described in arXiv:hep-th/0403039, the extended version of…

Weyl's scale invariance: Inflation, dark matter and dark energy connections

We show that the standard model extended to include Weyl’s symmetry as a local symmetry and an additional neutral scalar singlet can account for the puzzles pertaining to inflation, dark matter, and…

Two-measure approach to breaking scale-invariance in a standard-model extension

Small dark energy and stable vacuum from Dilaton–Gauss–Bonnet coupling in TMT

In two measures theories (TMT), in addition to the Riemannian measure of integration, being the square root of the determinant of the metric, we introduce a metric-independent density $$\Phi $$Φ in…

Weyl geometric gravity and 'breaking' of electroweak symmetry

A Weyl geometric scale covariant approach to gravity due to Omote, Dirac, and Utiyama (1971ff) is reconsidered. It can be extended to the electroweak sector of elementary particle fields, taking into…

Conformal symmetry and the Standard Model

Very narrow shadow extra Z boson at colliders

We consider the phenomenological consequences of a hidden Higgs sector extending the standard model (SM), in which the 'shadow Higgs' are uncharged under the SM gauge groups. We consider a simple…

Shadow Higgs boson from a scale-invariant hidden U(1)s model

We study a scale-invariant SU(2)xU(1){sub Y}xU(1){sub s} model which has only dimensionless couplings. The shadow U(1){sub s} is hidden, and it interacts with the standard model (SM) solely through…

Standard Model and SU(5) GUT with Local Scale Invariance and the Weylon

Weyl’s scale invariance is introduced as an additional local symmetry in the standard model of electroweak interactions. An inevitable consequence is the introduction of general relativity coupled to…

Broken scale invariance in the standard model

We introduce Weyl's scale invariance as an additional local symmetry in the standard model of electroweak interactions. An inevitable consequence is the introduction of general relativity coupled to…

Gauge and gravitational interactions with local scale invariance

Local scale invariance as a fundamental symmetry of Nature is proposed. This necessitates the existence of a new vector boson associated with local scale invariance. The new boson is referred to as…
