AbstractAbstract
[en] We use Laplace sum rules to find the values of masses and widths of the lowest scalar glueball compatible with the present knowledge of the vacuum condensates. Our results favour the existence of a light (M < ∼ 0.7 GeV) and narrow (Γ < ∼ 0.06 GeV) lowest scalar glueball. As a byproduct we estimate the value of the eight dimension condensate, the result being in contradiction with the one obtained using the vacuum saturation hypothesis. (author)
