Glueball-glueball scattering and the glueballonium


  • Mr. Enrico TROTTI

Primary authors



We study the scattering of two scalar glueballs within the dilaton potential model, that depends on a single parameter $\Lambda_G$. We unitarize to predict the lowest partial waves in the elastic window. These can be compared with lattice calculations, to validate the model and the connection of $\Lambda_G$ to the gluon condensate. We investigate the possible emergence of a bound state, called glueballonium, showing its existence for suitable $\Lambda_G$.
