C. Alexandrou, M. Constantinou, V. Drach, K. Hatziyiannakou, K. Jansen, C. Kallidonis, G. Koutsou, T. Leontiou, A. Vaquero
A review of recent nucleon structure calculations within lattice QCD is presented. The nucleon excited states, the axial charge, the isovector momentum fraction and helicity distribution are discussed, assessing the methods applied for their study, including approaches to evaluate the disconnected contributions. Results on the spin carried by the quarks in the nucleon are also presented.
