The Lepton-Photon symposiums - as represented by the contributions in this volume - are among the most popular conferences in high energy physics since they give an in-depth snapshots of the status of the field as provided by leading experts. This volume covers the latest results on flavor factories, quantum chromodynamics (QCD), electroweak physics, dark matter searches, neutrino physics and cosmology, from a phenomenological point of view. It also offers a glimpse of the immediate future of the field through summaries on the status of the next generation of high energy accelerators and planned facilities for astroparticle physics. The review nature of the articles makes the volume particularly useful to students, as well as being of interest to established researches in high-energy physics and related fields.
