Several experimental facilities are now exploring new energy regimes of particle physics. This volume discusses the potentials of planned and hypothetical facilities in light of the newest theoretical and experimental developments. The work also provides reports from the interrelated disciplines of particle physics and cosmology. It contains outstanding papers on the latest theoretical ideas and speculation concerning the physics that may lie beyond the Standard (Glashow-Weinberg-Salam) Model. Also contained are excellent reviews of plans and ideas on future accelerators, as well as surveys on current experimental searches. The book covers the most exciting areas of physics beyond the Standard Model: neutrino masses and mixing, dark matter, future colliders - Tevatron upgrades, LHC, new developments in QCD, electroweak symmetry breaking - strongly-coupled WW Sector, dynamical symmetry breaking, origins of flavor physics, Fermion mass patterns, supersymmetry, superstring and supergravity boundary conditions and constraints, heavy quark physics, b-factory physics, CP violation, new physics through the t quark, anomalous couplings, applications of effective lagrangians, anomalous gauge couplings, renormalons, baryogenesis, black holes, and quantum gravity.
