Conformal theory of MacDowell-Mansouri type

We describe a MacDowell-Mansouri mechanism of breaking symmetry in application to gauge theory with conformal group in 4D. Conformal symmetry is broken down and leave only the Lorentz symmetry preserved. The dynamical structure of theory reconstruct the results of Weyl action, but with addition of the branch of topological constants as well as Holst term.
