Implications of the conformal Higgs model (2112.10770v2)

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.
