• Using the Bethe-Salpeter equation, we study the bound states of the Faddeev-Popov ghost in the Euclidean SU (2) gauge theory. A Lagrangian in a nonlinear gauge has an additional ghost interaction. It is shown that this interaction yields the massless bound state c^^-×c at the scale Λ_<QCD>. We also show that it is impossible to obtain the bound states c×c and c^^-×c^^-, even if an additional interaction exists.
