Abstract
We study improved variational wave functions for SU(3) Hamiltonian lattice gauge theory by comparing variational ground-state energies and scalar-glueball masses. Variational wave functions that include twisted six-link Wilson loops and plaquettes are significantly better than those that include only plaquettes for calculating the ground-state energy and the scalar-glueball mass. The calculated glueball mass approaches scaling, suggesting that further improvements can be made by including more loops.
