Atomic parity violation: the seventh decade — •Dmitry Budker — Helmholtz Institute, JGU Mainz and UC Berkeley

Parity violation (PV) in atoms was considered by Ya. B. Zel'dovich in 1959, shortly after the discovery of parity violation in beta decay. However, a realistic experimental approaches and the first observations of the effects we only made in the 1970s. Today, atomic parity violation is a subfield of precision measurements, while observation of PV in molecules remains an unmet challenge. We will discuss what motivates present-day atomic and molecular experiments and mention a few of the ongoing and proposed experiments.
