Book Description
Jefferson Laboratory has the potential to make a dramatically improved measurement of parity violation in Moeller scattering (e + e â e + e). In the context of the Standard Model, the measurement would yield the best determination of sin2  W at low energy ( sin2  W = ±0.00025), and one of the best at any energy scale. As a new physics search via the running of the weak mixing angle, the experiment would have unparalleled sensitivity to new parity-violating e? e interactions, probing electron substructure to 29 TeV (95% CL). In terms of specific models, pulls of 6A are allowed in R-parity violating SUSY, about 5A in E6 Z2, and almost 3A in R-parity conserving SUSY. The latter makes an improved Moeller measurement complementary to searches for SUSY loop-induced Electric Dipole Moments. Interpretability limits are well below the projected experimental error. A conceptual design for a 12 GeV JLab experiment is presented.

Book Description
This book contains the proceedings of the third international workshop on From Parity Violation to Hadronic Structure and More. The many applications of parity violation are way beyond the scope of what Lee and Yang could have imagined fifty years after their proposal. For the physics topics discussed during this workshop, the application of parity violation has become a standard work horse allowing for the extraction of many physics topics in different experiments.
