Description

Using recent results obtained within the hidden gauge formalism for vector mesons, in which the f0(1370) and f2(1270) resonances are dynamically generated resonances from the ρρ interaction, we evaluate the radiative decay of these resonances into γγ. We obtain results for the width in good agreement with the experimental data for the f2(1270) state and a width about a factor 2 smaller for the f0(1370) resonance, which is also in agreement with the data of the Crystal Ball Collaboration and with the more recent ones from the Belle Collaboration, which, however, have a very large uncertainty.
