Inclusive distributions and two particle correlations in e+ e- annihilation at 29 GeV center-of-mass energy

The author has studied hadron production in e+ e- annihilation at 29 GeV center-of-mass energy using the PEP-4 Time Projection Chamber Detector. The inclusive sections and mean multiplicities for π +/-, K +/- and (p + anti p) production have been measured using ionization energy loss to separate particle species. The author finds on average 10.7 +/- 0.6 π +/-, 1.35 +/- .13 K +/- 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, the author has observed correlations in rapidity space for identified pions and kaons. Short-range KK correlations provide evidence for local flavor compensation during hadronization. Long-range ππ and KK correlations indicate that the initial partons carry flavor. The author also observed significant long-range πK correlations as a result of heavy quark decays
