TLDR
Measurement of parity-violating asymmetries in elastic electron-proton scattering indicate nonzero, Q2 dependent, strange-quark contributions and provide new information beyond that obtained in previous experiments.Abstract:
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 ≤ Q^2 ≤ =1.0 GeV^2. These asymmetries, arising from interference of the electromagnetic and neutral weak interactions, are sensitive to strange-quark contributions to the currents of the proton. The measurements were made at Jefferson Laboratory using a toroidal spectrometer to detect the recoiling protons from a liquid hydrogen target. The results indicate nonzero, Q^2 dependent, strange-quark
contributions and provide new information beyond that obtained in previous experiments.read more

Chiral Perturbation Theory and Baryon Properties
TL;DR: Theoretical and experimental progress has been made in describing the properties of baryons in the low-energy domain this paper, and two non-perturbative methods are privileged frameworks for studying their properties in this domain: chiral perturbation theory, the effective field theory of the Standard Model at energies below 1 GeV and lattice QCD.
