Exclusive production of proton-antiproton pairs by two photon scattering at CM energies between 2.0 GeV and 3.1 GeV has been measured with the TASSO detector at the e+e- storage ring PETRA. The angular distribution is flat within the accepted CM angu

Samples of ∼1,900 identified protons and ∼500 Λ have been used to search for decuplet baryon production in e+e- annihilation at a c.m. energy of 34.4 GeV. The p π+ and Λ π± invariant mass spectra contain no Δ or Σ* signals. Upper limits, a

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
