Scattering polarized electrons provides an important probe of the weak interactions. Precisely measuring the parity-violating left–right cross-section asymmetry (ALR) is the goal of a number of experiments that have recently been completed or are in progress. The experiments are challenging, given that ALR is small, typically between 10−4 and 10−8. By carefully choosing appropriate targets and kinematics, one can isolate various pieces of the weak Lagrangian, providing a search for physics…
