摘要
The gravitational field h_(μν)with spin-2 is introduced naturally by the requirement that the Lagrangian is locally translation invariant in Minkowski spacetime.The interactions between the h_(μν)and spin-1/2,0,1 matter fields are obtained along with the Lagrangian for the gravitational field including self-interactions.The deflection angle of light when it passes through the sun is calculated with different gauge conditions as an example.Our leading-order result is the same as that from general relativity,although the basic ideas are different.It is interesting that gravity can be described in a similar way to other fundamental interactions in Minkowski spacetime,and it may provide a new scenario for the Universe.
