2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/103361We present recent Monte Carlo data for the axial charge of the nucleon obtained by the QCDSF-UKQCD collaboration for N_f=2 dynamical quarks. We compare them with formulae from chiral perturbation theory in finite and infinite volume and find a remarkably consistent picture.6 pages, 3 figures, talk presented at Lattice2005 (weak matrix elements), needs PoS.clsHigh Energy Physics - LatticeThe axial charge of the nucleon on the lattice and in chiral perturbation theorytext
