Conformal Higgs model: Gauge fields can produce a 125GeV resonance (1304.4650v5)

Abstract: 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 nonclassical gravitational terms. Conformal theory accounts both for observed excessive external galactic orbital velocities and for accelerating cosmic expansion. SU(2) symmetry-breaking is retained but dark energy is implied rather than nonzero Higgs particle mass. These results are compatible with existence of a massive neutral particle or resonance $W_2$ at 125GeV, described as composite scalar $g_{\mu\nu}W_-^\mu W_+^\nu$ and $g_{\mu\nu}Z^{\mu*}Z^\nu$ interacting strongly via quark exchange. Decay modes would be consistent with those observed at LHC. Higgs scalar field $\Phi$ is dressed by the $W_2$ field to produce Lagrangian term $\lambda(\Phi^\dagger\Phi)^2$.
