Abstract

The spectrum of glueballs with quantum numbers JPC=0±+,2±+,3±+,4±+J^\mathsf{PC}=0^{\pm+},2^{\pm+},3^{\pm+},4^{\pm+} is calculated in quenched quantum chromodynamics from bound state equations. The input is taken from a parameter-free calculation of two- and three-point functions. Our results agree well with lattice results where available and contain also some additional states. For the scalar glueball, we present first results for the effects of additional diagrams which turn out to be strongly suppressed.
