Experiment E04-113 at Jefferson Lab Hall C plans to measure the beam-target double-spin asymmetries in semi-inclusive deep-inelastic [rvec p](e, e[prime]h)X and [rvec d](e, e[prime]h)X reactions (h = [pi][sup +], [pi][sup -], K[sup +] or K[sup -]) with a 6 GeV polarized electron beam and longitudinally polarized NH[sub 3] and LiD targets. The high statistic data will allow a spin-flavor decomposition in the region of x = 0.12 [approx] 0.41 at Q[sup 2] = 1.21 [approx] 3.14 GeV[sup 2]. Especially, leading-order and next-to-leading order spin-flavor decomposition of [Delta]u[sub v], [delta]d[sub v] and [delta][bar u] - [Delta][bar d] will be extracted based on the measurement of the combined asymmetries A[sub 1N][sup [pi][sup +]-[pi][sup -]]. The possible flavor asymmetry of the polarized sea will be addressed in this experiment.

Experts on elementary-particle physics, both theorists and experimentalists, met to present their latest results on the various aspects of HERA physics, specifically, the H1 and ZEUS collaborations at HERA and the collaborations at LEP and the Tevatron were presented. The topics included: proton structure function; polarized "ep" scattering; final states in deep-inelastic scattering (DIS), with special emphasis on jet production at low x, power corrections in DIS, soft particle production, and instanton effects; photon structure function; photoproduction of jets and hadrons; heavy-flavour and charmonium production; elastic and diffractive ep scattering; and new physics at HERA.

Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.

In the last few years there has been considerable progress in improving the accuracy of parity violation experiments in electron scattering at high energy and in atomic physics. Recent results are a challenge to the standard electroweak theory and our understanding of hadron structure. This book is an extensive review of the advances in this field. The theoretical framework is presented at a pedagogical level, experiments and future projects are reviewed, and the results and their interpretation are discussed in depth.
