  We study the interactions of the pseudoscalar glueball with scalar and
pseudoscalar quark-antiquark meson fields and with the nucleon and its chiral
partner. In both cases we introduce the corresponding chiral Lagrangian and
discuss its properties. We calculate the mesonic and baryonic decays of a
pseudoscalar glueball with mass of about 2.6 GeV as predicted by Lattice
simulations.
