A mixing scheme for the structure of f0(600) and f0(1370)

Within the framework of a nonlinear chiral Lagrangian we explore the nontrivial nature of f0(600) and f0(1370) in terms of quarkonium, tetraquark and gluonium components. The mass constraints are obtained and the strong and radiative partial widths are calculated to demonstrate and discriminate these components. The static properties of f0(1500) and glueball are also studied. Our results are confronted with the experimental and theoretical data available as well as the upcoming measurements.
