Abstract

We study the contribution of instantons to the binding and the mass of the lightest scalar glueball, in gluon dynamics. We show that the short-range correlations introduced by such non-perturbative vacuum fluctuations are sufficient to give rise to a scalar glueball bound state, with a mass in good agreement with the results of recent lattice calculations.
