Abstract
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 at the scale ΛQCD. We also show that it is impossible to obtain the bound states c × c and ¯ × ¯, even if an additional interaction exists.
