THE GLUEBALL SPECTRUM AND SCALING IN SU(3) LATTICE GAUGE-THEORY

Abstract:

We calculate glueball masses and the string tension on lattices as large as 204 and at couplings as small as β= 6 g2=6.2. To be able to do so we construct wave-functionals that maintain a good overlap with the long-distance physics as the lattice spacing is made small. Our calculations strongly indicate that the lightest glueball is the 0++ and that the next highest levels are a nearly degenerate 2++ and 0-+ at roughly 1.6m[0++]. In addition there is a 1+- just below 2m[0++]. The mass of the ...
