| الوصف: | We extensively study the ultraviolet quantum properties of a nonlocal action for gravity nonminimally coupled to matter. The theory unifies matter and gravity in an action principle such that all the classical solutions of Einstein's theory coupled to matter are also solutions of the nonlocal theory. At the quantum level, we show that the theory is power-counting super-renormalizable in even dimensions and finite in odd dimensions. A simple extension of the model compatible with the above properties is finite also in even dimensions. Comment: 52 pages. v2: abstract simplified, terminology denoting the extremals changed, some parts clarified, new section 6.4 added, conclusions unchanged. Accepted for publication in JHEP |
