概要 | Using recent results obtained within the hidden gauge formalism for vector mesons, in which the f(0)(1370) and f(2)(1270) resonances are dynamically generated resonances from the rho rho interaction, we evaluate the radiative decay of these resonances into gamma gamma. We obtain results for the width in good agreement with the experimental data for the f(2)(1270) state and a width about a factor 2 smaller for the f(0)(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. |
