Description
The quantitative understanding of hadron structure holds the key to the interpretation of current and future experiments in particle, hadron and nuclear physics, which provide crucial information for the search for New Physics. In this talk I review the status of lattice QCD calculations of structural properties of the nucleon, focussing on the determination of electromagnetic and axial form factors, calculations of the axial, scalar and tensor charges, as well as the determination of sigma-terms. A central issue for precision calculations of these quantities is control over excited state contributions that may cause a systematic bias in results.
