MOLLER - Moller Experiment

Program Description: The MOLLER experiment at Jefferson Laboratory proposes to measure the parity-violating asymmetry in electron-electron (Møller) scattering. The measurement would be carried out by rapidly flipping the longitudinal polarization of electrons that have been accelerated to 11 GeV at CEBAF, and observing the resulting fractional difference in the probability of these electrons scattering off atomic electrons in a liquid hydrogen target. The asymmetry is proportional to the weak charge of the electron, which in turn is a function of the electroweak mixing angle, a fundamental parameter of the electroweak theory. The accuracy of the proposed measurement will provided a measurement of the mixing angle with precision on par with the two single best measurements of the same parameter at electron-positron colliders. Under construction at Jefferson Lab, expected to become operational in 2017 and operate for 3-4 years.
