  • The internal structure of the neutron has now been probed by highly energetic photons scattering off it. Combined with previous results for protons, these measurements reveal the contributions of quark flavours to the nucleon structure.

  • A comparison of electron scattering from the mirror nuclei hydrogen-3 and helium-3 reveals that proton–proton pairs have a much larger contribution to short-range correlations in helium-3 than in heavier nuclei, implying an unexpected nuclear structure.

  • It remains a challenge to find the structure and the distribution of the constituents of nucleons. Here the authors use a scattering method to get information about the gluons and quarks inside a proton and separate the contribution of Bethe-Heitler from the deeply virtual Compton scattering process.

  • Measurement of the asymmetry in the parity-violating scattering of polarized electrons on protons gives the weak charge of the proton as 0.0719 ± 0.0045, in agreement with the standard model.
