Renormalization in quantum Brans-Dicke gravity
arXiv:hep-th/0205130
Abstract
In the Brans-Dicke model we treat the scalar field exactly and expand the gravitational field in a power series. A comparison with 2D sigma models and ϕ^{4} perturbation theory in four dimensions suggests that the perturbation series in 4D Brans-Dicke model is renormalizable.
