Description
The process γγ -> π+π- has been measured with complete particle identification. Cross-sections are presented from near threshold up to the region of the f(1270). In the mass range 0.5-0.7 GeV, cross-sections are lower than the Born term predictions and show no evidence for an epsilon(600). The two-photon width of the f(1270) is found to be in agreement with previous results. (orig.)
