abstract = {We report the first Lattice QCD calculation using the
almost physical pion mass mπ=149 MeVmπ=149 MeV that agrees
with experiment for four fundamental isovector observables
characterizing the gross structure of the nucleon: the Dirac
and Pauli radii, the magnetic moment, and the quark momentum
fraction. The key to this success is the combination of
using a nearly physical pion mass and excluding the
contributions of excited states. An analogous calculation of
the nucleon axial charge governing beta decay has
inconsistencies indicating a source of bias at low pion
masses not present for the other observables and yields a
result that disagrees with experiment.},
