Description

The threshold enhancement in the cross section γγ → rho0rho0, including the lower energy point reported by the CELLO group, and the observed angular distributions have been interpreted in terms of an isoscalar resonance with Jsup(PC) = 0++, mass 1450-1550 MeV and with 100-150 MeV. (orig.)
