Description

A nuclear anapole moment (NAM)--a magnetic moment associated with a localized toroidal current--arises due to hadronic parity violating interactions between nucleons. The NAM can be detected via the coupling of its local magnetic field to the spin of a penetrating electron, such as an unpaired valence electron in a neutral atom. ZOMBIES is an experiment to measure NAMs using neutral polar molecules, where the NAM serves to mix hyperfine/rotational states of opposite parity. A magnetic field is used to apply Zeeman shifts that bring these states to near degeneracy, leading to parity-violating asymmetries of order unity. This talk will describe a proof-of-principle measurement with ZOMBIES, and prospects for near- and long-term measurements of many NAMs using this approach.
