spontaneous symmetry breaking

[spän′tā·nē·əs ′sim·ə·trē ‚brāk·iŋ]
(physics)
A situation in which the solution of a set of physical equations fails to exhibit a symmetry possessed by the equations themselves; an example is a magnet, in which the underlying equations describing the metal do not distinguish any direction of space from any other, but the magnet certainly does, since it points in some definite direction.

Obviously, there is a zero mode, and we have only one massless vector field in the theory after symmetry breakdown.
