It is about 18 months since the discovery of the first psi particle at SPEAR (Augustin et al. 1974; Abrams et al. 1974) and at BNL (Aubert et al. 1974). During this time, the e/sup +/e/sup -/ colliding-beam experiments have found a huge amount of new information on this new layer of hadron structure...

description It is about 18 months since the discovery of the first psi particle at SPEAR (Augustin et al. 1974; Abrams et al. 1974) and at BNL (Aubert et al. 1974). During this time, the e/sup +/e/sup -/ colliding-beam experiments have found a huge amount of new information on this new layer of hadron structure: nine states with widths ranging from tens of kilovolts to many megavolts, the principal decay modes and quantum numbers of some of the states, limits on charmed-particle production, mu e events, etc. The author discusses the new states, the total hadron cross section, and the mu e events. The work considered has been done by the SLAC/LBL magnetic detector group at the SPEAR e/sup + /e/sup -/ storage ring of the Stanford Linear Accelerator Center. (17 refs).
