The Qweak collaboration is currently performing the first precision measurement of the proton's neutral weak charge at Jefferson Lab. The Standard Model gives a firm prediction for the weak charge; any deviation from that can be interpreted as new physics beyond the Standard Model. This precision, low energy measurement is sensitive to new physics signatures at energy scales up to 2 TeV. The...

Hadrons are complex systems of confined quarks and gluons and exhibit the characteristic spectra of excited states. Quantum Chromodynamics (QCD) is only poorly understood in this non-perturbative regime. It is one of the key issues in hadronic physics to identify the relevant degrees of freedom giving rise to the observed mass spectra and the effective forces between them. Current efforts of...

As the lightest particle in the hadron spectrum, the pi^0 plays an important role in understanding the fundamental symmetries of QCD. The pi^0 --> gamma gamma decay provides a key process for test of the chiral anomaly, and at the same time a test of the Nambu-Goldstone nature of the pi^0 meson due to spontaneous chiral symmetry breaking. Theoretical activities over the last decade have...
