TL;DR: Scattering experiments show that in carbon-12 the neutron-proton pairs are nearly 20 times as prevalent as proton- Proton pairs and, by inference, neutron-neutron pairs, which has implications for understanding cold dense nuclear systems such as neutron stars.

TL;DR: In this article, the parity-violating asymmetry in fixed target electron-electron (Moeller) scattering was measured at the Z{sup 0} pole, and the running of the weak mixing angle was observed with over 6σ significance, which sets constraints on new physics effects at the TeV scale.

TL;DR: In this article, the first measurement of target single spin asymmetries in the semi-inclusive ^3He(e,e^′π^±)X reaction on a transversely polarized target was reported.

TL;DR: In particular, the polarization transfer results have exposed the limits of applicability of the one-photon exchange approximation and highlighted the role of quark orbital angular momentum in the nucleon structure.

TL;DR: The first measurements of the e[over -->]p-->epgamma cross section in the deeply virtual Compton scattering (DVCS) regime and the valence quark region are presented, proving that generalized parton distributions (GPDs) are accessible to experiment at moderate Q(2), and the first model-independent measurement of linear combinations of GPDs and GPD integrals up to the twist-3 approximation.
