Abstract

We report on a high statistics measurement of the total and differential cross sections of the process γγ → π ⁺π ^- in the π ⁺π ^- invariant mass range 0.8 GeV/c ² < W < 1.5 GeV/c ² with 85.9 fb ^-1 of data collected at √s = 10.58 GeV and 10.52 GeV with the Belle detector. A clear signal of the f ₀(980) resonance is observed in addition to the f ₂(1270) resonance. An improved 90% confidence level upper limit ℬ(η′(958) → π ⁺π ^- < 2.9 × 10 ^-3 is obtained for P- and CP-violating decay of the η′(958) meson using the most conservative assumption about the interference with the background.
