Atomic parity violation in one single radium ion — •Rob Timmermans — KVI, University of Groningen

The photon-Z0 mixing angle is a fundamental parameter of the unified electroweak theory. Its renormalization group ``running'' from high to low energy is a poorly tested prediction of the Standard Model. A high-precision measurement of the electroweak mixing angle at low momentum scales is possible by monitoring quantum jumps in one single trapped radium ion with precision laser techniques, and observing the coherent weak charge of the quarks via the effects of parity-forbidden transitions. We discuss the particle-physics and atomic theory, and the feasibility of a definitive parity-violation experiment at the TRImP facility at KVI.
