Book Description
In the framework of light-cone QCD rules, we study the valence quark distribution function {ital q}({ital x}{sub B}) of a pion for moderate {ital x}{sub B}. The sum rule with the leading twist-2 wave function gives {ital q}({ital x}{sub B}) = [phi]{sub {pi}}({ital x}{sub B}). Twist-4 wave functions give about 30% for {ital x}{sub B} ≈0.5. It is shown that QCD sum rule predictions, with the asymptotic pion wave function, are in good agreement with experimental data. We found that a two-hump profile for the twist-2 wave function leads to a valence quark distribution function that contradicts experimental data.

Book Description
This volume contains the proceedings of the 'Workshop on Lightcone QCD and Nonperturbative Hadron Physics', held in Adelaide, Australia, in December 1999. The contributions include papers on vacuum structure and zero modes, DLCQ, deep inelastic scattering, lightcone wavefunctions and hadron structure, hadron phenomenology, as well as numerical results from the lattice for both quenched and unquenched QCD.

Book Description
This book provides an up-to-date, self-contained account of deep inelastic scattering in high-energy physics, intended for graduate students and physicists new to the subject. It covers the classic results which led to the quark-parton model of hadrons and the establishment of quantum chromodynamics as the theory of the strong nuclear force, in addition to new vistas in the subject opened up by the electron-proton collider HERA. The extraction of parton momentum distribution functions, a key input for physics at hadron colliders such as the Tevatron at Fermi Lab and the Large Hadron Collider at CERN, is described in detail. The challenges of the HERA data at 'low x' are described and possible explanations in terms of gluon dynamics and other models outlined. Other chapters cover: jet production at large momentum transfer and the determination of the strong coupling constant, electroweak interactions at very high momentum transfers, the extension of deep inelastic techniques to include hadronic probes, a summary of fully polarised inelastic scattering and the spin structure of the nucleon, and finally a brief account of methods in searching for signals 'beyond the standard model'.

Book Description
We present results for leading-twist azimuthal asymmetries in semi-inclusive lepton-nucleon deep-inelastic scattering due to naively time-reversal odd transverse-momentum dependent parton distribution functions from the light-cone constituent quark model. We carefully discuss the range of applicability of the model, especially with regard to positivity constraints and evolution effects. We find good agreement with available experimental data from COMPASS and HERMES, and present predictions to be tested in forthcoming experiments at Jefferson Lab.

Book Description
This book constitutes the proceedings of a workshop on 'Exclusive and Semi-exclusive Processes at High Momentum Transfer', sponsored by the Institute for Nuclear Theory (Seattle) and the Thomas Jefferson National Accelerator Facility (Jefferson Laboratory). The workshop was inspired by recent progress in the field, particularly in the uses of off-forward or skewed parton distributions to elucidate nucleon structure. This book contains the written versions of 41 scientific talks, on subjects including the aforementioned skewed parton distributions, and also on deeply virtual Compton scattering, semi-exclusive (or semi-inclusive) reactions, and hard elastic and transition form factors.

Book Description
This volume focusses on four main topics: structure functions, tests of quantum chromodynamics, physics at the highest Q2 and p2T, and high energy scattering and diffraction. Comprehensive review articles on hadronic and photon structure, lepton-parton and parton-parton physics as well as future experimental opportunities are presented, together with a special lecture on HERA's legacy after the first decade of operation.
