Book Description
The structure of neutrons, protons, and other strongly interacting particles in terms of their quark and gluon constituents can be calculated from first principles by solving QCD on a discrete space-time lattice. With the advent of SciDAC software and prototype clusters and of DOE supported dedicated lattice QCD computers, it is now possible to calculate physical observables using full QCD in the regime of large lattice volumes and light quark masses that can be compared with experiment. This talk will describe selected examples, including the nucleon axial charge, structure functions, electromagnetic form factors, the origin of the nucleon spin, the transverse structure of the nucleon, and the nucleon to Delta transition form factor.
