This talk reports a search for the production by ee− annihilation of a single photon accompanied by particles that interact only weakly in matter. The search was performed at PEP (..sqrt..s = 29 GeV) with a new detector, ASP. No unexpected signal was observed. The limit N/sub nu/ 51 GeV/c2 (90% CL) for m/sub approx ... gamma../ = O and degenerate approx.e mass states. 7 refs., 4 figs.

We have studied hadron production in ee− annihilation at 29 GeV center-of-mass energy using the PEP-4 Time Projection Chamber Detector. The inclusive cross sections and mean multiplicities for .pi./sup + -/, K/sup + -/ and (p + anti p) production have been measured using ionization energy loss to separate particle species. We find on average 10.7 +- 0.6 .pi./sup + -/, 1.35 +- 13 K/sup + -/ and 0.60 +- 0.08 (p + anti p) per multihadron event. The differential cross section is well described by a number of Monte Carlo hadronization models. In addition, we have observed correlations in rapidity space for identified pions and kaons. Short-range KK correlations provide evidence for local flavor compensation during hadronization. Long-range .pi pi. and KK correlations indicate that the initial partons carry flavor. We also observe significant long-range .pi. K correlations as a result of heavy quark decays. 85 references, 67 figures, 11 tables.
