Description
Based on the general principles of Lorentz symmetry and unitarity, we introduce two consistency conditions -- on-shell gauge symmetry and strong massive-massless continuation -- in constructing amplitudes of massive gauge theory with elementary particles. In particular we argue that on-shell gauge symmetry can be understood as a consequence of Lorentz symmetry, unitarity and massive-massless continuation. Based on these two conditions, combined with the little group transformation and consistent factorization, we construct 3-point and 4-point vector-boson/scalar amplitudes that correspond to renormalizable interactions, then analyze the underlying theories and models. The corresponding theories include gauge symmetry with S.S.S and Stueckelberg theory. In particular, when the number of vector boson is larger than 3, the theory must be Yang-Mills theory with S.S.B.
