  The aim of this work is to discuss and explore some generalized aspects of
generation of photon mass respecting gauge symmetry. We introduce generalized
Stueckelberg and Higgs gauge theories and present the classical and quantum
frameworks related to them. We construct the quantum theory by writing the
transition amplitude in the Fadeev-Senjanovic formalism and put it in a
covariant form by the Fadeev-Popov method. We also analyze the independence of
the transition amplitude by gauge parameters via BRS-T symmetry. Even in the
generalized context, the Stueckelberg structure influences the quantization
process of the Higgs theory in the 't Hooft's fashion, in which an intimate
relationship between the Stueckelberg compensating field and the Goldstone
boson arises.
