Hard processes in photon-photon collisions are studied using high statistics data without requiring an electron tag. A high yield of hadrons with pt in the range 1.5-3.0 GeV/c is observed. This yield exceeds the expectation of the Born term by a fact

Production of proton-antiproton pairs by two-photon scattering has been observed at the electron-position storage ring PETRA. A total of eight proton-antiproton pairs have been identified using the time-of-flight technique. We have measured a total c
