Abstract

We summarize the present status of testing the standard model of parity nonconservation in neutral atoms, emphasizing the success in understanding the semileptonic weak interactions. There is good agreement for the nuclear spin independent contributions, especially in cesium. There is some evidence of nuclear spin dependent terms, probably due to hadronic weak interactions. There is no evidence of leptonic weak interactions. The lessons learned from atomic physics are discussed, together with strategies for parity experiments using highly charged ions.
