Book Description
While perturbative QCD methods fully describe experimental results at high energies, and chiral perturbation theory is the low energy effective theory of the strong interactions, a form of duality is observed connecting these two regimes. In these intermediate kinematics, a wide variety of reactions are observed which can be described simultaneously by single particle (quark) scattering, and by exclusive resonance (hadron) scattering.The contributions in this proceedings volume discuss recent and existing results, and aim to foster current and future research, investigating the phenomenon of quark-hadron duality.This unique volume contains research work by scientists from different arenas of hadronic physics, dealing with different manifestations of quark-hadron duality.

Book Description
This book is a graduate-level self-study guide of bound states in elementary particle physics and consequently in the standard model. The author first recalls the usual quantum electrodynamics (QED) approach to atoms in terms of Feynman diagrams, which assume free states at asymptotic times. Motivated by general principles and data, he then develops a novel method based on a Fock expansion of bound states in temporal gauge. The properties of relativistic bound states are discussed for Dirac states, atoms in motion, QED in D=1+1 dimensions, and hadrons in quantum chromodynamics (including color confinement). This book provides complementary material for quantum field theory courses and is accessible for graduate students and more senior researchers.

Book Description
DIS 2005 is the 13th in a series of annual workshops on Deep Inelastic Scattering (DIS) and Quantum Chromodynamics (QCD). The aim of these workshops is to review the progress in the field of DIS and QCD and to discuss and lay the groundwork for the future. DIS 2005 brought together 280 experimentalists and theorists to discuss the latest theoretical developments and new experimental results from HERA, TeVatron, SLAC, CERN, RHIC and Jefferson Lab.

Book Description
This volume is centered on recent developments in the exploration of hadronic structure through lepton scattering, in the description of hadron physics directly from lattice QCD and non-perturbative QCD models, and in efforts to strengthen the links between these activities. Specific topics that are covered include: parton distribution functions, polarized structure functions, generalized structure functions, nuclear effects, quark-hadron duality, electromagnetic form factors, structure functions and hadron properties from lattice QCD, and QCD models based on the DysonOCoSchwinger equations. Contents: Partonic Structure of Hadrons: Chiral Extrapolation of Lattice Structure Function Calculations (W Detmold); Exclusive Processes at HERMES (N Bianchi); Soft Pion Production Associated with Deeply Virtual Compton Scattering (L Mosse); Spin Structure of Hadrons: Polarized Structure Functions in QCD (J Kodaira); Single Spin Asymmetries and Quark Fragmentation (M Anselmino et al.); Perturbative OCo Nonperturbative QCD Transition: Lepton Scattering and Quark-Hadron Duality Studies at Jlab (R Ent); Estimating Low Energy Model Parameters from Deep Inelastic Scattering (L P Hoyt & A I Signal); Form Factors: Physical Hadron Properties from Lattice Data at Large Quark Masses (A W Thomas); Electromagnetic Interactions in Light Front Dynamics (J -F Mathiot); Nucleon Form Factors in the Covariant Diquark-Quark Model (R Alkofer & M Oettel); Hadron Excitations, Confinement and Chiral Symmetry Breaking: Experimental Studies of the Hadron Spectrum (J Napolitano); The Character of Goldstone Bosons (M B Hecht et al.); Deconfining by Winding (R Hofmann); Small- x Physics and Nuclear Medium Effects: Leading Nucleon Production at HERA (G Levman); Nuclear Medium Effects at HERMES (P di Nezza); Physics Motivation for a Polarized Electron-Ion Collider (J M Cameron & J T Londergan); and other papers.

Book Description
Experiments at CEBAF will scan the intermediate-energy region of the QCD dynamics for the nucleon form factors and for Compton Scattering. These experiments will definitely clarify the role of resumed perturbation theory and of quark-hadron duality (QCD sum rules) in this regime. With this perspective in mind, the authors review the factorization theorem of perturbative QCD for exclusive processes at intermediate energy scales, which embodies the transverse degrees of freedom of a parton and the Sudakov resummation of the corresponding large logarithms. They concentrate on the pion and proton electromagnetic form factors and on pion Compton scattering. New ingredients, such as the evolution of the pion wave function and the complete two-loop expression of the Sudakov factor, are included. The sensitivity of their predictions to the infrared cutoff for the Sudakov evolution is discussed. They also elaborate on QCD sum rule methods for Compton Scattering, which provide an alternative description of th is process. They show that, by comparing the local duality analysis to resumed perturbation theory, it is possible to describe the transition of exclusive processes to perturbative QCD.
