The Test Of The Background Field In The Universe With The Particle Physics Method

In this dissertation,we have made the reseach on the test of the background field in the universe with the particle physics method.By the coupling betwwen the background scalar field and the quantized gauge field,we obtained the modified formula of the particle's static mass with the fluctuation of the background field.We also gave a primary advice on the experimental test of our method.Firstly,we introduced background knowlede of the cosmology and the situation of the dark energy resaech and various dark energy model.We proposed a particle physics method to test the backgroud scalar field in the universe.Secondly,we introduced the Higss mechanism,including the representation of the left hand and right hand fermion,option of gauge group,the coupling of Higss field and gauge field,the coupling of Higgs field and lepton field and quark field,the extent of Higgs particle's mass and the experimental test of the Higgs mechanism.We discussed the constraint on the classical backgroud field,including the conservation of energy momentum and charge,non Goldstone boson.By the analogy to the Higss mechanism in the standard model,we introduced the coupling between the bachground scalar field in the universe and quantized gauge field.We obtained the modified formula of particle's static mass with the fluctuation of the background fied.Finally,we gave a primary advice on the experimental test on the modified formula of particle's static mass.We also discussed possible experimental consequences.
