Determination of radiative widths of scalar mesons from experimental results on gamma gamma -> pi pi

The scalar mesons in the 1 GeV region constitute the Higgs sector of the st rong interactions. They are responsible for the masses of all light flavour hadrons. However, the composition of these scalar states is far from clear . despite decades of experimental effort. The two photon couplings of the f (0)'s are a guide to their structure. Two photon results from Mark II: Crys tal Ball and CELLO prompt a new Amplitude Analysis of gamma gamma --> pi(+) pi(-), pi(0) pi(0) cross-sections. Despite their currently limited angular coverage and lack of polarized photons, we use a methodology that provides the nearest one can presently achieve to a model-independent partial wave separation. We find two distinct classes of solutions. Both have very simil ar two photon couplings for the f(0)(980) and f(0)(400 - 1200). Hopefully t hese definitive results will be a spur to dynamical calculations that will bring us a better understanding of these important states.
