Abstract
We formulate a framework to determine the mass of glueball states of the Landau gauge Yang-Mills theory in the continuum. To this end we derive a Bethe-Salpeter equation for two gluon bound states including the effects of Faddeev-Popov ghosts. We construct a suitable approximation scheme such that the interactions in the bound state equation match a corresponding successful approximation of the Dyson-Schwinger equations for the Landau gauge ghost and gluon propagators. Based upon a recently obtained solution for the propagators in the complex momentum plane we obtain results for the mass of the ${0}^{++}$ and ${0}^{\ensuremath{-}+}$ glueballs. In the scalar channel we find a mass value in agreement with lattice gauge theory.
