Abstract
In this paper, we have proposed the theory of gravity gauge, and the gravity theory has been introduced into quantum field theory. We have further given the tensor equation of gravity field in the flat space, and found the gravity field equation is the Lorentz covariant and gauge invariant. The gravity theory can be quantized and can be unified with the electroweak and strong interaction at a new gauge group .
Highlights
Open AccessThe Einstein’s general theory of gravity (GR) is treated as geometry of curved space-time, which appears to provide a successful macroscopic description of all known gravitational phenomena; it is of interest to explore alternative theories that may provide a more fundamentally appealing description or suggest new experiments leading to the discovery of new phenomena [1] [2]

We give the equation of gravity tensor field at the flat Minkowski spacetime, and further prove the gravity field equation is the Lorentz covariant and gauge invariant
Summary
The Einstein’s general theory of gravity (GR) is treated as geometry of curved space-time, which appears to provide a successful macroscopic description of all known gravitational phenomena; it is of interest to explore alternative theories that may provide a more fundamentally appealing description or suggest new experiments leading to the discovery of new phenomena [1] [2]. [17], the authors have taken into consideration a generalization of gauge theories based on the analysis of the structural characteristics of Maxwell theory, which is based on few principles related to different orders of commutators between covariant derivatives They have modified theory of gravity, in which the algebra of operators of covariant derivatives leads to an additional term in the equation of motion associated with the non-conservation of the energy-momentum tensor. In order to introduce the gravity gauge field, we should add a term of partial derivative ∂μ∂ν in Dirac equation and. The ∂μ should be make the transformation as Equation (5), it only introduce the vector gauge field Aμ ( x). 571 Journal of High Energy Physics, Gravitation and Cosmology by Equation (36), the gauge transformation of gravity is ( ) φμ=′v φμν 1 g. At U(1) gauge transformations (10) and (11), the Equation (50) should be introduced the electromagnetism and gravity gauge fields (18) and (19), and the gravity gauge transformation (37)
