Conformal Symmetry and Unification
Marek Pawlowski (Soltan Institute for Nuclear Studies, Warsaw)
TL;DR
This paper introduces a conformal symmetry-based extension of the Standard Model that unifies gravity and particle physics, replacing the Higgs mechanism with a conformal gauge scale fixing, and predicts new Weyl vector bosons.
Contribution
It presents a novel conformal gauge symmetric model unifying gravity and the Standard Model, replacing the Higgs mechanism with a geometric scale fixing, and predicts Weyl vector bosons.
Findings
Scalar field is non-dynamical and lacks observable quantum excitations.
Cosmological constant arises naturally from the scalar quadratic term.
Weyl vector bosons can mix with photon and weak bosons.
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 Penrose-Chernikov-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.
