Summary Reducible fieldsA(x) with degenerate vacuum which allow the unitary-symmetry transformationU −1(c)A(x)U(c)=A(x)+c are analysed. We describe the mathematical properties of the « charge integral » related to the conserved current of this spontaneously broken symmetry. Further we discuss the structure of theS-matrix theory in such a generalized field theory as a guide-line for the treatment of more complex examples of spontaneously broken symmetries.
