Description:

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, we need to analyse the nucleon's 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 the point where a synthesis of the results is indispensable. With this book, A. W. Thomas (University of Adelaide, Australia) and W. Weise (Technical University of Munich, Germany) give 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.

The object of these studies is to understand how nucleons are constituted from interacting quarks and gluons, and to predict their properties (charge distribution, magnetic moment, spin, resonances …).

Several experiments have shown that the quarks only contribute of the order of 30% of the spin of the nucleon. Nucleon, either of the subatomic particles, the proton and the neutron, constituting atomic nuclei. Protons (positively charged) and neutrons (uncharged) behave identically under the influence of the short-range nuclear force, both in the way they are bound in nuclei and in the way they are scattered by each other.This strong interaction is independent of electric charge. Structure functions and parton distributions In the parton model the nucleon in the e-N interaction can be considered as a the result of partonic currents, such as: Assuming only u,d,s quarks in the proton this corresponds to: The same formulas apply for the neutron, but with different parton The nucleon-nucleon interaction and all effective interactions used in practice have certain symmetries. They are invariant by translation (changing the frame of reference so that directions are not altered), by rotation (turning the frame of reference around some axis), or parity (changing the sense of axes) in the sense that the interaction does not change under any of these operations ...

The structure of the nucleon. Full Record; Other Related Research; Abstract. Experimental data on electromagnetic and weak form factors of the nucleon are analyzed in a two-component model with a quark-like intrinsic structure surrounded by a meson cloud. The contribution from strange quarks is discussed and compared with recent data from the G0 Collaboration.
