Implications of the conformal Higgs model

TL;DR

The conformal Higgs model, based on local Weyl symmetry, offers a modified gravity and Higgs framework that explains cosmic acceleration and galaxy rotation without dark matter, aligning with observations and predicting a composite gauge boson.

Contribution

This paper introduces the conformal Higgs model, integrating Weyl symmetry into gravity and Higgs theory, providing explanations for dark energy and galaxy rotation curves without dark matter.

Findings

Fits observed accelerating Hubble expansion with one parameter

Explains galaxy rotation curves without dark matter

Predicts a composite gauge boson at 125 GeV

Abstract

The postulate of universal local Weyl scaling (conformal) symmetry modifies both general relativity and the Higgs scalar field model. The conformal Higgs model (CHM) acquires a cosmological effect that fits observed accelerating Hubble expansion for redshifts $z\leq 1$ (7.33 Gyr) accurately with only one free constant parameter. Conformal gravity (CG) has recently been fitted to anomalous rotation data for 138 galaxies. Conformal theory explains dark energy and does not require dark matter, providing a viable alternative to the $\Lambda$CDM standard paradigm. The theory precludes a massive Higgs particle but validates a composite gauge field $W_2$ with mass 125GeV.
