Almost All

The possibility of measuring the scale parameter of quantum chromodynamics, Λs, at CHEER is discussed. Rationale for the measurement of this quantity are given, along with a discussion of the theoretical difficulties involved. The measurement of the Q2 dependence of structure functions and their moments, and methods of measuring αs and its Q2 evolution, are discussed, and arguments are given for the advantages and disadvantages of going to high Q2 values at CHEER. It is concluded that while sensitivity to Λ is lowered at high Q2, CHEER will, in principle, be able to provide the first clean measurements of Λ, free from almost all the theoretical confusion involved in interpretations of present data.

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.

Minimum Sensitivity

The corrections implied by quantum chromodynamics to parton model predictions are not unique to finite order in perturbation theory on account of the possibility of choosing different renormalization schemes. Stevenson has provided a criterion for selecting the "best" renormalization procedure; the so-called "principle of minimum sensitivity" (PMS). This criterion is applied here to the Q2-dependent part of the moments of the nonsinglet structure functions in lepton–hadron scattering.
