The Dvali-Gabadadze-Porrati (DGP) model with additional terms in the action is considered. These terms have a special form and include auxiliary scalar fields without kinetic terms, which are nonminimally coupled to gravity. The use of these fields allows one to exclude the mode, which corresponds to the strong coupling effect, from the theory. Effective four-dimensional theory on the brane appears to be the same, as in the original DGP model.
