Description
We investigated the two scalar glueball
scattering and the possible emergence of a bound state,
that we call glueballonium. The scalar glueball, the lightest particle of the
YM sector of QCD, has a lattice predicted mass of about
$m_{G}\simeq1.7$ GeV. We performed this study in the context of a
widely used dilaton potential, that depends on a single dimensionful parameter $\Lambda_G$. The unitarization considered by us allowed us to predict the lowest partial waves in the elastic window. Furthermore, we
also show that a glueballonium forms if $\Lambda_{G}$ is small enough. In particular, for
$\Lambda_{G}$ compatible with the expectations from the gluon condensate, the glueballonium has a mass of about $3.4$ GeV.
