Renormalizable Quantum Gauge General Relativity

arXiv:gr-qc/0309041

Abstract

The quantum gauge general relativity is proposed in the framework of quantum gauge theory of gravity. It is formulated based on gauge principle which states that the correct symmetry for gravitational interactions should be gravitational gauge symmetry. The gravitational gauge group is studied in the paper. Then gravitational gauge interactions of pure gravitational gauge field is studied. It is found that the field equation of gravitational gauge field is just the Einstein's field equation. After that, the gravitational interactions of scalar field, Dirac field and vector fields are studied, and unifications of fundamental interactions are discussed. Path integral quantization of the theory is studied in the paper. The quantum gauge general relativity discussed in this paper is a perturbatively renormalizable quantum gravity, which is one of the most important advantage of the quantum gauge general relativity proposed in this paper. A strict proof on the renormalizability of the theory is also given in this paper. Another important advantage of the quantum gauge general relativity is that it can explain both classical tests of gravity and quantum effects of gravitational interactions, such as gravitational phase effects found in COW experiments and gravitational shielding effects found in Podkletnov experiments. For all classical effects of gravitational interactions, such as classical tests of gravity and cosmological model, quantum gauge general relativity gives out the same theoretical predictions as that of the Einstein's general relaitvity.
