Higher spin glueballs from functional methods
2021
We calculate the glueball spectrum for spin up to J =4 and positive charge
parity in pure Yang-Mills theory. We construct the full bases for J =0,1,2,3,4
and discuss the relation to gauge invariant operators. Using a fully
self-contained truncation of Dyson-Schwinger equations as input, we obtain
ground states and first and second excited states. Where available, we find
good quantitative agreement with lattice results.
