| Abstract: | The problem of the ground state of the SU(2) Yang-Mills theory is investigated within the one-loop approximation. It is shown that an assumed initial constant magnetic field will be diminished to realize a state of lower energy (vacuumI) by a condensation of some components of Yang-Mill fields. We also find a Lorentz invariant state (vaccumII) through a singlet scalar condensation. However, the vaccumI which is Lorentz noinvariant is found to have a lower energy density than the vacuumII. |
