We show that key results of supersymmetry can be achieved via conformalsymmetry. We propose that the Higgs boson be a dynamical bound state ratherthan an elementary scalar, so that there is no quadratic divergence self-energyproblem for it and no need to invoke supersymmetry to resolve it. We study aconformal invariant theory of interacting fermions and gauge bosons, in whichthere is scaling with anomalous dimensions and dynamical symmetry breaking,with the dynamical dimension of $\bar{\psi}\psi$ being reduced from 3 to 2.With this reduction we augment the theory with a then renormalizable 4-fermioninteraction with dynamical dimension equal to 4. We reinterpret the theory as arenormalizable version of the Nambu-Jona-Lasinio (NJL) model, with the gaugetheory sector with its now massive fermion being the mean field and the4-fermion interaction being the residual interaction. It is this residualinteraction that generates dynamical Goldstone and Higgs states, states that,as noted by Baker and Johnson, the gauge theory sector itself does not possess.The Higgs boson is found to be a narrow resonance just above threshold. Wecouple the theory to conformal gravity, with the interplay between conformalgravity and the 4-fermion interaction taking care of the vacuum energy problem.With conformal gravity being a consistent quantum gravity theory there is noneed for string theory with its supersymmetric underpinnings. With conformalgravity fits to galactic rotation curves and the accelerating universe notneeding dark matter, there is no need to introduce supersymmetry for either thevacuum energy problem or to provide a potential dark matter candidate. Wepropose that it is conformal symmetry rather than supersymmetry that isfundamental, with the theory of nature being a locally conformal, locally gaugeinvariant, non-Abelian NJL theory.
