Gravitational renormalization of quantum field theory
نویسنده
چکیده
We propose to include gravity in quantum field theory non-perturbatively by modifying the propagators so that each virtual particle in a Feynman graph move in the space-time determined by the momenta of the other particles in the same graph. We then obtain a modified Feynman propagator for the massless neutral scalar field which shows a suppression at high momentum strong enough to entail finite results to all loop orders for processes involving at least two virtual particles.

Testable Consequences of Curved-Spacetime Renormalization
I consider certain renormalization effects in curved spacetime quantum field theory. In the very early universe these effects resemble those of a cosmological constant, while in the present universe they give rise to a significant finite renormalization of the gravitational constant. The relevant renormalization term and its relation to elementary particle masses was first found by Parker and T...
متن کاملGauge Theory of Gravity
The quantum gravity is formulated based on principle of local gauge invariance. The model discussed in this paper has local gravitational gauge symmetry and gravitational field appears as gauge field. The problems on quantization and renormalization of the theory are also discussed in this paper. In leading order approximation, the gravitational gauge field theory gives out classical Newton’s t...
متن کاملPhysical Scaling and Renormalization Group in Two-Dimensional Gravity
Quantum gravitational effects on the renormalization group equation are studied in the (2+ ǫ)-dimensional approach. Divergences in a matter one-loop effective action do not receive gravitational radiative corrections. The renormalization factor for beta functions recently found by Klebanov, Kogan and Polyakov is obtained by using the renormalized cosmological constant to define the physical sca...
متن کاملGauge Fixing and Renormalization in Topological Quantum Field Theory*
In this letter we show how Witten’s topological Yang-Mills and gravitational quantum field theories may be obtained by a straightforward BRST gauge fixing procedure. We investigate some aspects of the renormalization of the topological Yang-Mills theory. It is found that the beta function for the Yang-Mills coupling constant is not zero. Submitted to Phys. Lett. * Work supported by the Departme...
متن کاملScaling behavior of the cosmological constant : Interface between quantum field theory and cosmology Ilya
In quantum field theory, the vacuum action is subject to renormalization and to the renormalization group running. Consequently, the “cosmological constant” is not a constant, still less should be zero. In this paper we continue with previous work, and derive the contributions of the light particles to the running of the cosmological and gravitational constants in the Standard Model, from the c...
متن کاملCosmological Constant Problems and Renormalization Group
The Cosmological Constant Problem emerges when Quantum Field Theory is applied to the gravitational theory, due to the enormous magnitude of the induced energy of the vacuum. The unique known solution of this problem involves an extremely precise fine-tuning of the vacuum counterpart. We review a few of the existing approaches to this problem based on the account of the quantum (loop) effects a...
