초록

We report on a high statistics measurement of the total and differential cross sections of the process gamma gamma -> pi+pi- in the pi+pi- invariant mass range 0.8 GeV/c(2) < W < 1.5 GeV/c 2 with 85.9fb(-1) of data collected at root 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(eta '(958) -> pi(+)pi(-)) < 2.9 x 10(-3) is obtained for P- and CP-violating decay of the eta '(958) meson using the most conservative assumption about the interference with the background.
