We have studied hadron production in e + e~ annihilation at 29 GeV center-of-mass energy using the PEP-4 Time Projection Chamber Detector. The inclusive cross sections and mean multi plicities for n ± , K ± and (p + p) production have been measured using ionization energy loss to separate particle species. We find on average 10.7±0.6 jr±, 1.3S±.13K ± and 0.60 ± 0.08 (p-f-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 com pensation during hadronization. Long-range nir and KK correlations indicate that the initial partons carry flavor. We also observe significant long-range jrK correlations as a result of heavy quark decays.
