Recent experimental and theoretical developments in the understanding of high energy diffraction, presented in the working group on diffraction at DIS98 in Brussels, are summarised. A template, giving the definition of the most commonly used kinematical variables in diffraction, which was provided in the working group sessions, is reproduced as a appendix. References to original papers may be found within the individual contributions.
In this summary of the considerations of the QCD working group at Snowmass 2001, the roles of quantum chromodynamics in the Standard Model and in the search for new physics are reviewed, with empahsis on frontier areas in the field. We discuss the importance of, and prospects for, precision QCD in perturbative and lattice calculations. We describe new ideas in the analysis of parton distribution functions and jet structure, and review progress in small-$x$ and in polarization.
A summary is given of the experimental and theoretical results presented in the working group on spin physics. New data on inclusive and semi-inclusive deep-inelastic scattering, combined with theoretical studies of the polarized distribution functions of nucleons, were presented. Many talks addressed the relatively new subjects of transversity distributions and generalized parton distributions. These distributions can be studied by measuring single spin asymmetries, while partonic intrinsic motion and models of new spin dependent distribution and fragmentation functions are needed to obtain the corresponding theoretical description. These subjects are not only studied in deep-inelastic lepton scattering, but also in polarized proton-proton collisions at RHIC. A selection of results that have been obtained in these experiments together with several associated theoretical ideas are presented in this paper. In conclusion, a brief sketch is given of the prospects for experimental and theoretical studies of the spin structure of the nucleon in the coming years.
