摘要：
We have measured the cross section for pi(+) pi(-) production in two-photon collisions using a data sample with an integrated luminosity of 85.9 fb(-1) collected with the Belle detector. The f(0)(980) resonance is observed as a peak in the energy spectrum of the cross section. We also report preliminary results for gamma gamma -> pi(0)pi(0) with two-photon center-of-mass energies ranging from 0.6 to 4.0 GeV, based oil a 95 fb(-1) data sample.
