Abstract: Using the improved lattice gauge field Hamiltonian and the truncated eigenvalue equation method, we compute the 0++ glueball wave function of three-dimensional U(1) lattice gauge theory up to the 3rd order. The scaling behavior of the 3rd order result is much better than the one of the 2nd order result.
