The radiative decays phi to gamma a_0 / f_0 in the molecular model for the scalar mesons
The radiative decays phi to gamma a_0 / f_0 in the molecular model for the scalar mesons
We investigate the radiative decays of the phi-meson to the scalar mesons a(0)(980) and f(0)(980). We demonstrate that, contrary to earlier claims, these decays should be of the same order of magnitude for a molecular state and for a compact state and, therefore, the available experimental informati...

We investigate the radiative decays of the phi-meson to the scalar mesons a(0)(980) and f(0)(980). We demonstrate that, contrary to earlier claims, these decays should be of the same order of magnitude for a molecular state and for a compact state and, therefore, the available experimental information is consistent with both a molecular as well as a compact structure of the scalars. Thus, the radiative decays of the phi-meson into scalars establish a sizable K K component of the scalar mesons, but do not allow to discriminate between molecules and compact states. |
