“…The SM Higgs mass is replaced in calculations by an effective cutoff that can be expressed (eliminated) by some measured quantity or a combination of observables. 1-loop predictions for 12 LEP observables were given in [18] in reasonable agreement with SM and experiment.…”

Abstract.The Weyl-Weinberg-Salam model is presented. It is based on the local conformal gauge symmetry. The model identifies the Higgs scalar field in SM with the PenroseChernikov-Tagirov scalar field of the conformal theory of gravity. Higgs mechanism for generation of particle masses is replaced by the originated in Weyl's ideas conformal gauge scale fixing. Scalar field is no longer a dynamical field of the model and does not lead to quantum particle-like excitations that could be observed in HE experiments. Cosmological constant is naturally generated by the scalar quadric term. The model admits Weyl vector bosons that can mix with photon and weak bosons.

“…This choice, although possible, is not compulsory for the analysis of a Higgs-like mechanism which couples ew-bosons to gravity [20], neither does it seem advisable. The similarity of this approach to the one of [29] which relies on unbroken conformal scale covariance and a conformally weakened gravitational action, indicates that this type of coupling does not depend on the scale breaking condition w(M 0 ) = 0 for a scalar field mass. Therefore it seems preferable to assume M 0 = 0 (or if M 0 = 0, gauge weight w(M 0 ) = −1 and M 0 ≡ λ 2 ), in order to keep closer to the Weyl geometric setting.…”

“…This is a conceptually convincing alternative to the usual Higgs mechanism. In similar approaches, Hung Cheng [24] and Pawlowski and Raczka [29] have arrived at similar expressions by deriving mass terms perturbatively on the tree level from the same scale invariant Lagrangian without the Mexican hat potential. This is a remarkable agreement.…”

A Weyl geometric approach to cosmology is explored, with a scalar field φ of (scale) weight −1 as crucial ingredient besides classical matter. Its relation to Jordan-Brans-Dicke theory is analyzed; overlap and differences are discussed. The energy-stress tensor of the basic state of the scalar field consists of a vacuum-like term g μν with depending on the Weylian scale connection and, indirectly, on matter density. For a particularly simple class of Weyl geometric models (called EinsteinWeyl universes) the energy-stress tensor of the φ-field can keep space-time geometries in equilibrium. A short glance at observational data, in particular supernovae Ia (Riess et al. in Astrophys. J. 659:98ff, 2007), shows encouraging empirical properties of these models.

Weyl geometric gravity and electroweak symmetry “breaking”

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 account their basic scaling freedom. Already Cheng (1988) indicated that electroweak symmetry breaking, usually attributed to the Higgs field with a boson expected at 0.1 − 0.3 T eV , may be due to a coupling between Weyl geometric gravity and electroweak interactions. Weyl geometry seems to be well suited for treating questions of elementary particle physics, which relate to scale invariance and its "breaking". This setting suggests the existence of a scalar field boson at the surprisingly low energy of ∼ 1 eV . That may appear unlikely; but, as a payoff, the acquirement of mass arises as a result of coupling to gravity in agreement with the understanding of mass as the gravitational charge of fields.
