Estimates of SU(2) Glueballs on a Coarse, Anisotropic Lattice

Using Tadpole-improved lattice action, the low-lying glueball spectrum of the pure-gauge SU(2) theory is calculated on an anisotropic lattice. The results of m(0⁺), m(2⁺), and m(0^-) are consistent with that for the Wilson action on much larger lattices. This shows the advantage of using the coarse, anisotropic lattice to calculate the glueball masses.
