Nucleon structure from lattice QCD
School of Physics, University of Edinburgh, Edinburgh, EH9 3JZ, UK
The aim of these lectures will be to provide an introductory overview of the concepts needed to compute hadronic matrix elements on the lattice from which moments of Generalised Parton Distributions (GPDs) are extracted and to highlight the contributions that current lattice calculations are making to this exciting field of research. Interesting related topics that will be covered include recent work on the nucleon electromagnetic form factors and moments of parton distribution functions, including the nucleon's axial coupling constant, gA, and the average fraction of the nucleon's momentum carried by the quarks, 〈 xq〉.
