WAVE-FUNCTION AND GLUEBALL MASSES IN QCD - THE 3-DIMENSIONAL CASE

We try to develop a possibly more efficient way for extracting the wav efunction and spectroscopy of pure QCD from discretized Hamiltonian fi eld theory. By further exploring the eigenvalue equation method for so lving the Schrodinger equation, we find that within this approach a mo re suitable choice of the glueball operators can lead to significantly much better results, therefore more rapid convergence to the continuu m limit. This is nicely demonstrated in the three-dimensional example.
