On the mass of the glueballonium
Enrico Trotti, Francesco Giacosa
According to lattice simulations and other theoretical approaches, the scalar glueball is the lightest state in the Yang-Mills sector of QCD. Since within this sector the scalar gl…

Glueball-glueball scattering and the glueballonium
Francesco Giacosa, Alessandro Pilloni, Enrico Trotti
The scalar glueball is the lightest particle of the Yang-Mills sector of QCD, with a lattice predicted mass of about GeV. It is natural to investigate glueball…

Constraints imposed by the partial wave amplitudes on the decays of mesons
Vanamali Shastry, Enrico Trotti, Francesco Giacosa
We study the two-body decays of mesons using the covariant helicity formalism. In particular, we show how the partial wave analysis of decays constrains the interacting terms enter…
