Book Description
Z° bosons have been produced by collisions of longitudinally polarized electrons with unpolarized positrons at the SLAC Linear Collider and their decays have been recorded by the SLD experiment. We present preliminary measurements of the properties of the resulting Z° decays into multi-hadronic final states. We find good agreement with the predictions of perturbative QCD and fragmentation models.

Book Description
The authors have measured the differential cross sections for the production of [pi]{sup {+-}}, K{sup {+-}}, K°, K*(892), [phi](1,020), p and [Lambda] in hadronic Z° decays and in subsets of flavor-tagged Z° → light quark (u{anti u}, d{anti d}, or s{anti s}), Z° → c{anti c} and Z° → b{anti b} events. Charged hadrons were identified with the SLD Cherenkov ring imaging detector. The vertex detector was employed to select flavor enriched samples and the polarized electron beam from SLC was used to tag quark and anti-quark jets. The authors observe a flavor dependence in the hadron fragmentation functions. The authors present evidence for leading particle production in hadronic decays of the Z° boson to light-flavor jets and a direct measurement of the strangeness suppression factor [gamma]{sub s}.

Book Description
Multiparticle dynamics is tightly connected with the fundamental properties of the QCD vacuum. This was reflected in the Scientific Programme of the XXVIII International Symposium on Multiparticle Dynamics. Emphasis was given during the sessions to the collective phenomena at high energies, including: fluctuations and correlations, quark-gluon plasma, QCD phase transitions (fractals, intermittency, wavelets), the QCD structure of the Pomeron, and new aspects of multiplicity distributions.

Book Description
The authors have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow them to make the most precise determination of the b-quark fragmentation function, using ee− {r{underscore}arrow} Z° decays recorded in the SLD experiment at SLAC. The authors compared their measurement with the predictions of a number of fragmentation models. The authors excluded several of these models and measured the average scaled energy of weakly-decaying B hadrons to be (x{sub B}) = 0.714"0.005(stat)"0.007(syst)"0.002 (model-dependence).

Book Description
The 32nd International Conference on High Energy Physics belongs to the Rochester Conference Series, and is the most important international conference in 2004 on high energy physics. The proceedings provide a comprehensive review on the recent developments in experimental and theoretical particle physics. The latest results on Top, Higgs search, CP violation, neutrino mixing, pentaquarks, heavy quark mesons and baryons, search for new particles and new phenomena, String theory, Extra dimension, Black hole and Lattice calculation are discussed extensively. The topics covered include not only those of main interest to the high energy physics community, but also recent research and future plans.
