The weak force is the only fundamental interaction known to violate the symmetry with respect to spatial inversion (parity). This parity violation can be used to isolate the effects of the weak interaction in atomic systems, providing a unique, low-energy test of the standard model (see, for example, reviews1–3). These experiments are primarily sensitive to the weak force between the valence electrons and the nucleus, mediated by the neutral Z0 boson and dependent on the weak charge of the…
