Gauge theory in a symmetrized chromomagnetic vacuum

It is found that a restriction of the Fock space to states invariant under space and $\mathrm{SU}\mathrm{}\left(N\right)\mathrm{}$ rotations stabilizes the Savvidy vacuum. The symmetrized Hamiltonian is canonically quantized and a Fock space is formally constructed. The one-loop contributions to the effective Lagrangian and the energy of the vacuum are calculated. The quark-quark classical potential is found to vanish.
