The Vacuum of Lattice Gauge Theory with Fermions and Spontaneous Chiral Symmetry Breaking

The vacuum structure of lattice gauge theory with fermions is studied by the variational method. The fermion condensate is given as a function of .

Unitary Transformations in Lattice Gauge Theory with Fermions and the Meson Spectrum

The Hamiltonian of lattice gauge theory with fermions is diagonalized in the one-link approximation and the meson spectrum of SU(N) theory with one flavor is derived.

Glueball masses from Hamiltonian lattice QCD

We calculate the masses of the and glueballs from QCD in 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 , from which we estimate and .We calculate the masses of the
