Translation gauge field theory of gravity in Minkowski spacetime

Hang LiP. Wang
Mar 2023
摘要
The gravitational field with spin-2 is introduced naturally by therequirement that the Lagrangian is locally translation invariant in Minkowskispacetime. The interactions between avitational field and spin-1/2, 0, 1 matterfields are obtained as well as the Lagrangian for the gravitational fieldincluding self-interactions. The deflection angle of light when it passesthrough the sun is calculated with different gauge conditions as an example.Our leading-order result is the same as that from general relativity though thebasic ideas are quite different. It is interesting that gravity could bedescribed in the similar way as the other fundamental interactions in Minkowskispacetime and it may provide new scenario of the Universe.
