Review of e+e--physics with PETRA

Selected results from the PETRA electron-positron storage ring are described. Searches for several postulated particles including the top quark, the bottom prime quark, excited leptons, heavy leptons, magnetic monopoles, supersymmetric and Higgs particles have given negative results but provided new mass limits. In electroweak and weak interactions, lepton asymmetry, heavy quark asymmetry, and coupling constants have been explored and new data obtained for Tau and heavy quark semileptonic decay branching ratios. Results for strong interactions include new data on total hadronic cross sections, hadronic final states, jet properties, baryon number compensation and the fragmentation function for heavy quarks. In two photon physics, the two photon decay widths of mesons, hadron pair production and the photon structure function have been studied
