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.

We search for the production of a heavy W(prime) gauge boson that decays to third generation quarks in 0.9 fb−1 of p{bar p} collisions at (square root)s = 1.96 TeV, collected with the D0 detector at the Fermilab Tevatron collider. We find no significant excess in the final-state invariant mass distribution and set upper limits on the production cross section times branching fraction. For a left-handed W(prime) boson with SM couplings, we set a lower mass limit of 731 GeV. For right-handed W(prime) bosons, we set lower mass limits of 739 GeV if the W(prime) boson decays to both leptons and quarks and 768 GeV if the W(prime) boson decays only to quarks. We also set limits on the coupling of the W(prime) boson to fermions as a function of its mass.

The ISMD 2005 conference reviewed and updated the theoretical and experimental understanding of multiparticle production in high energy collisions. About half of the papers discussed collisions of ultra-relativistic nuclei with recent results from RHIC. In addition, some intriguing results from HERA and Tevatron colliders were presented and future experiments were discussed as well. Following the ISMD conference, the Workshop on Particle Correlations and Femtoscopy was held for the first time. This new series of regular workshops presents a critical and thorough analysis of the latest results on particle interferometry in high energy heavy ion collisions. Thefocus on this rather narrow subject was stimulated by a wealth of new data arriving steadily from the RHIC and SPS experiments.
