• We investigate the possibility that the perturbative vacuum is unstable against gauge boson pair condensation in non-Abelian gauge theories without fundamental scalar fields. The force law between gauge boson pairs is studied in the Coulomb gauge. Assuming that the pairs condense in channels of attractive gauge force, we investigate the patterns of spontaneous symmetry breakdown in the SU(N) and SO(2N) gauge theories. As a possible application of this symmetry breaking scheme, we consider SU(5) and SO(10) gauge models of grand unification without fundamental scalar fields. It is found that the desirable breaking patterns SU(5)→SU(3)×SU(2)×U(1) and SO(10)→SO(6)×O(4)→SU(3)×SU(2)×SU(2)×U(1) arise as a result of gauge boson pair condensation. Our mechanism is also applicable to GUTs with massless fundamental scalars, in which supercooling of the Universe would last up to extremely low temperature.
