Narrow Results

Recent cosmological observations and compatible theory offer an understanding of long-mysterious dark matter and dark energy. The postulate of universal conformal local Weyl scaling symmetry, without dark matter, modifies action integrals for both Einstein–Hilbert gravitation and the Higgs scalar field by gravitational terms. Conformal theory accounts for both observed excessive external galactic orbital velocities and for accelerating cosmic expansion. SU(2) symmetry-breaking is retained by the conformal scalar field, which does not produce a massive Higgs boson, requiring an alternative explanation of the observed LHC 125 GeV resonance. Conformal theory is shown here to be compatible with a massive neutral particle or resonance $W_2$ at 125 GeV, described as binary scalars $g_{\mu \nu }{W}_{-}^{\mu }{W}_{+}^{\nu }$ and $g_{\mu \nu }{Z}^{\mu \ast }{Z}^{\nu }$ interacting strongly via quark exchange. Decay modes would be consistent with those observed at LHC. Massless scalar field $\mathrm{\Phi }$ is dressed by the $W_2$ field to produce Higgs Lagrangian term $\lambda {({\mathrm{\Phi }}^{†}\mathrm{\Phi })}^2$ with the empirical value of $\lambda$ known from astrophysics.
