Description

The major developments and achievements in two-photon physics obtained at the electron-positron colliders DORIS, SPEAR, PETRA and PEP are reviewed. These machines allowed for the first time detailed studies of hadron production in high-energy photon-photon collisions. With the advent of sufficiently high energies at PETRA and PEP the studies of resonant two-photon couplings were complemented by investigations of the perturbative QCD regime leading to the first observations of jet production and to measurements of the hadronic structure of the photon.
