โฆ Synopsis
We review the measurements of various two-photon processes at the Belle experiment. The measured cross sections are compared with various theoretical predictions based on the perturbative and non-perturbative QCD.

We have measured the cross section for ฯ + ฯ -production in two-photon collisions using a data sample with an integrated luminosity of 85.9 fb -1 collected with the Belle detector. The f0(980) resonance is observed as a peak in the energy spectrum of the cross section. We also report preliminary res
We have measured the mass, width and two-photon decay width of the ฮทc and ฮท c mesons in two-photon collisions using 483 fb -1 of data collected with the Belle detector at the asymmetric-energy e + e -collider KEKB. Interference effects have been studied.
