Book excerpt: Recent results on particle production in ee− annihilation at 29 GeV are reviewed. The data were obtained using the High Resolution Spectrometer at PEP and correspond to an integrated luminosity of 300 pb−1. The mean charged particle multiplicity in gluon jets from the three-jet events is found not to differ from that measured for quark jets. The production of the scalar meson S(975) and the tensor mesons f°(1270) and K*(1430) are observed and the rates are compared to the previously observed vector mesons, rho and K*(890). Finally, some of the global properties of charged particle production are presented and compared with similar results from soft hadronic collisions. 16 refs., 7 figs.
