The Structure of the Nucleon

As the only stable baryon, the nucleon is of crucial importance in particle physics. Since the nucleon is a building block for all atomic nuclei, there is a need to analyse the its structure in order to fully understand the essential properties of all atomic nuclei. After more than forty years of research on the nucleon, both the experimental and theoretical situations have matured to a point where a synthesis of the results becomes indispensable. Here, A.W. Thomas and W. Weise present a unique report on the extensive empirical studies, theoretical foundations and the different models of the nucleon. The appendices provide an extensive summary of formulae needed in practical calculations. From the contents: electromagnetic structure of the nucleon, weak probes of nucleon structure, deep inelastic lepton scattering on the nucleon; elements of QCD, aspects of non-perturbative QCD, Chiral Symmetry and nucleon structure, models of the nucleon

Nukleonen sind von umfassender Bedeutung für die Elementarteilchenphysik. Als Proton und Neutron sind sie Bausteine aller Atomkerne. Erst das Verständnis der Struktur von Nukleonen erklärt viele wesentliche Eigenschaften der Kerne.Mit diesem Buch gelingt es den Autoren Anthony W. Thomas (Universität von Adelaide, Australien) und Wolfram Weise (TU München, Deutschland), mehr als 40 Jahre der intensiven Forschung und den gegenwärtigen Stand der Ergebnisse zusammenzufassen. Erstmalig werden Erkenntnisse aus Theorie und Experiment zusammengeführt und so dem Leser ein Überblick über empirische Studien, theoretische Grundlagen und die verschiedenen Modelle geboten.
