摘要：
Euclidean SU(2) gauge theory is studied in a nonlinear gauge. In this theory, ghost condensation happens and gauge fields acquire tachyonic masses. It is shown that these tachyonic masses are removed by a gauge field condensate < A(mu)(+)A(mu)(-)> Because of the ghost condensation, monopole solutions are included naturally. We find that the condensate < A(mu)(+)A(mu)(-)> makes the magnetic potential massive
