Description
The MOLLER experiment aims to constrain fundamental parameters in the Standard Model by measuring the parity-violating asymmetry A$_{\rm PV}$ induced by the interference between electromagnetic and weak neutral current amplitudes. MOLLER will utilize polarized Møller scattering at Jefferson Lab to measure a highly precise 0.8 part per billion (ppb) uncertainty on the predicted 33 ppb A$_{\rm PV}$. This precision will yield a 2.4% determination of the electron’s weak charge and ultimately determine the weak mixing angle to 0.1% fractional uncertainty. As the most precise measurement of the weak mixing angle at low momentum transfer, the results will provide a unique probe into new, parity-violating physics at both MeV and multi-TeV scales. MOLLER has been designed to reach its precision through meticulous planning and the innovative design of its experimental apparatus—including the highest-power liquid hydrogen target to date, a toroidal spectrometer, and several detector systems capable of operating in tracking and integrating modes. This talk will outline the physics objectives, experimental design, and current status of construction efforts.
