TL;DR: In this article, distorted wave electron scattering calculations were used to extract the weak charge form factor FW($$\bar{q}$$), the weak radius RW, and the point neutron radius Rn, of 208Pb from the PREX parity violating asymmetry measurement.

TL;DR: The present experiment exploits the interference between the deeply virtual Compton scattering (DVCS) and the Bethe-Heitler processes to extract a linear combination of generalized parton distributions (GPDs) particularly sensitive to E_{q}, the least constrained GPD.

TL;DR: A measurement of the parity-violating asymmetry in electron–quark scattering yields a determination of 2C2u − C2d with a precision increased by a factor of five relative to the earlier result, providing evidence with greater than 95 per cent confidence that the C2q couplings are non-zero, as predicted by the electroweak theory.

TL;DR: Two-nucleon short-range correlated pairs are identified and their isospin structure is deduced as a function of missing momentum in a region where the nucleon-n nucleon (NN) force is expected to change from predominantly tensor to repulsive.
