In recent years the investigation of hadron structure using lattice techniques has attracted growing attention. The computation
of several important quantities has become feasible. Furthermore, theoretical developments as well as progress in algorithms
and an increase in computing resources have contributed to a significantly improved control of systematic errors. In this
article we give an overview on the work that has been carried out in the framework of the Hadron Physics I3 (I3HP) network
“Computational (lattice) hadron physics”. Here we will not restrict ourselves to spin physics but focus on results for nucleon
spectrum and structure from the QCDSF collaboration. For a broader overview of developments in this field see, e.g., [1]. 相似文献
