Quantum Electrodynamics Gauge invariant Lagrangian in the Presence of Gravitational Field

Abstract

In this work the standard model of particle physics Higgs boson in addition to fundamental forces in quantum theory are discussed the promotion of the standard model in all stages from starting with discoveries radioactivity and electron until discovering the higgs boson by high energy accelerator in CERN . Is also exhibited. In addition to the problem of Symmetry Breaking and Quantum gravity. In this work the effect of gravitational field is also incorporated through the mass term in the Lagrangian, beside redefining the guage transformation to make the lagrangian invariant.
