It is shown that spontaneous breaking of O(2) symmetry in a background metric of constant curvature R is accompanied by appearance of a Goldstone mode with mass squared of - 1 2R. If the gravitational field is coupled dynamically, the situation is quite similar and when spontaneous breaking of the O(2) symmetry takes place, a massive Goldstone mode appears in the antide Sitter background. A modified lagrangian yields a massless Goldstone mode and a flat background. If the O(2) symmetry is promoted to be local, the Higgs mechanism is responsible for the scalar and gauge field masses which include gravitational contributions.
