Description
The MOLLER experiment has been designed to significantly expand the reach for new dynamics beyond the Standard Model of electroweak interactions. Using the high intensity, high precision electron beam at Jefferson Lab, MOLLER measure the parity-violating asymmetry in the scattering of longitudinally polarized electrons off unpolarized electrons to an overall fractional accuracy of 2.4%. This measurement will be the most sensitive probe of new flavor- and CP-conserving neutral current interactions in the leptonic sector until the advent of a linear collider or neutrino factory. Fabrication of the novel spectrometer and detector packages is now well underway. This talk will summarize the principles of the experimental design, and report the current status of preparations toward the first physics run in early 2027.
