Glueball Masses from Hamiltonian Lattice QCD

Abstract

We calculate the masses of the $0^{++}$, $0^{--}$ and $1^{+-}$ glueballs from QCD in 3+1 dimensions using an eigenvalue equation method for Hamiltonian lattice QCD developed and described elsewhere by the authors. The mass ratios become approximately constants in the coupling region $6/g^2\in [6.0,6.4]$, from which we estimate $M(0^{--})/M(0^{++})=2.44\pm 0.05\pm 0.20$ and $M(1^{+-})/M(0^{++})=1.91\pm 0.05\pm 0.12$.
