The Gravity Gauge Theory and Gravity Field Equation in Flat Space

Abstract

In this paper, we have proposed the theory of ( ) 1 U 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
