Abstract

We present a study of the SU(3) glueball spectrum for all JPC values at lattice spacings down to a−1 = 3.73(6) GeV (β = 6.4) using lattices of size up to 324. We extend previous studies and show that the continuum limit has effectively been reached. The number of clearly identified JPC states has been substantially increased. There are no clear signals for spin-exotic glueballs below 3 GeV. A comparison with current experimental glueball candidates is made.
