Query: Constructing States and Effective Hamiltonians in Lattice QCD   We formulate SU(3) Hamiltonian lattice QCD in terms of the plaquette
variables and determine the relevant subspaces of the Hilbert space for the
vacuum wave functional and its approximations. We analyze the one- and
two-plaquette problems.
