Abstract

We calculate the masses of the 0⁺⁺, 0^-- and l^+- glueballs from QCD in 3+1 dimensions using an eigenvalue equation method for Hamiltonian lattice QCD developed and described by S.H. GUO et al. The mass ratios become approximately constants in the coupling region 6/g²∈[6.0,6.4], from which we estimate M(0^--)/M(0⁺⁺) = 2.44 ± 0.05 ± 0.20 and M(l^+-)/M(0⁺⁺) = 1.91 ± 0.05 ± 0.12.
