| Abstract: | Strong-coupling expansions, up to order g?4, for the off-axis glueball masses are developed in four-dimensional spacetime for lattice gauge theories with gauge groups SU(2), SU(3), Z2, Z3. Glueball mass spectra for the states 0++, 2++, 1+? are obtained. Restoration of Lorentz invariance is discussed. |
