The book provides a self-contained account of deep inelastic scattering (DIS) in high energy physics. It covers the classic results that lead to the quark-parton model of hadrons and the establishment of quantum chromodynamics (QCD), through to the 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 and Large Hadron Collider (LHC), is described in detail. The challenges of the HERA data at low-x are described, and possible explanations in terms of gluon dynamics outlined. Other chapters cover: jet production at large momentum transfer and the determination of the strong coupling constant; electroweak probes 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 a brief account of methods for searching for signals ‘beyond the standard model’.Less

This chapter reviews and puts into context the experiments which lead to the formulation of QCD. Starting from the static quark model, the phenomenology of deep inelastic scattering processes is introduced and used to derive and explain the quark parton model (QPM). Discussing in detail the conceptual problems of the QPM, the arguments that lead to the theory of strong interactions based on an SU(3) gauge symmetry are explained. The chapter concludes with the lagrangian of QCD.Less

In this chapter, the Rutherford scattering formula is derived using quantum mechanics. The kinematics of the quark–parton model (QPM) are described. The differential cross section for neutrino and antineutrino scattering on electrons is derived. This is generalized to give the QPM prediction for the cross section for scattering on nuclei. The key experiments supporting this model are reviewed with emphasis on the importance of scaling. Indirect and direct evidence for gluons is described. An elementary introduction to quantum chromodynamics (QCD) is given. The concept of running coupling constants is introduced in the context of QED and QCD. The concept of asymptotic freedom is used to explain the success of the QPM. Scaling violations are explained in terms of QCD, and a description is given of how the data can be used to determine the gluon distribution function. Finally, the QPM is generalized to the case of hadron–hadron scattering.Less
