Nucleon electromagnetic form factors at high Q2 from Wilson-clover fermions
The paper says
“Good agreement with experiment and phenomenology is found for the ratios GE/GM and F2/F1, whereas discrepancies are observed for the individual form factors F1 and F2.”

Abstract
We present results on the nucleon electromagnetic form factors from Lattice QCD at momentum transfer up to about 12 GeV2. We analyze two gauge ensembles with the Wilson-clover fermion action, a lattice spacing of a ≈ 0.09 fm and pion masses mπ ≈ 170 MeV and mπ ≈ 280 MeV. In our analysis we employ momentum smearing as well as a set of techniques to investigate excited state effects. Good agreement with experiment and phenomenology is found for the ratios GE/GM and F2/F1, whereas discrepancies are observed for the individual form factors F1 and F2. We discuss various systematics that may affect our calculation.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.
