Abstract
The glueball is investigated in four-dimensional SU(2) lattice gauge theory. Using a recently proposed source we carry out a high-statistics Monte Carlo calculation at β=2.25 and 2.40. We obtain reliable correlation up to distance t=2 and a signal/noise ratio >3 for correlation up to distance t=3. With increasing distances we find a significantly decreasing m) mass. There is no indication that the asymptotic limit (t→∞) has been reached.
