Query: Quenched glueball spectrum from functional equations   We give an overview of results for the quenched glueball spectrum from
two-body bound state equations based on the 3PI effective action. The setup,
which uses self-consistently calculated two- and three-point functions as
input, is completely self-contained and does not have any free parameters
except for the coupling. The results for
$J^{\mathsf{PC}}=0^{\pm+},2^{\pm+},3^{\pm+},4^{\pm+}$ are in good agreement
with recent lattice results where available. For the pseudoscalar glueball, we
present first results from a two-loop complete calculation, rendering also the
bound state calculation fully self-consistent.
