Some properties of gravity induced by dynamical symmetry breaking

If gravity arises as a consequence of quantum corrections of gauge theory it is necessary to take into account that the parameter ε of a non-minimal coupling of the scalar field φ with a curvature is the function ε(φ)=η+[e2/2(4π)2] [ln(φ2/μ2)-3]. The model allows for the chaotic inflation scenario. At η=e2/(4π)2 the rate of decrease of the gravitational constant is vertical strokeGvertical stroke/G<eH2/mP; in the postinflation epoch the structure of the theory practically coincides with that of Einstein's general relativity.
