Spin Structure Functions

These lectures discuss the substructure of the nucleon, first on the scale of 1 fermi and then at much shorter distances. We review relevant features of the quark model and introduce Quantum Chromodynamics and the idea of a running coupling. Recent data involving polarized protons is discussed in this framework, and an outlook is presented for future experiments relating to the spin substructure of the nucleon.

We revisit various topological issues concerning four-dimensional ungauged and gauged Wess-Zumino-Witten (WZW) terms for SU and SO quantum chromodynamics (QCD), from the modern bordism point of view. We explain, for example, why the definition of the 4d WZW terms requires the spin structure. We also discuss how the mixed anomaly involving the 1-form symmetry of SO QCD is reproduced in the low-energy sigma model.
