Description

Two new tabletop measurements promise to each increase by an order of magnitude the sensitivity for testing the SM and for probing for BSM (beyond the SM). For the electron magnetic moment, a one-electron relativistic quantum cyclotron already provides the most precise measurement — the most precisely measured property of any elementary particle — to test the most precise prediction of the SM. Quantum non-demolition (QND) measurements using quantum limited detectors and special relativity are at the heart of the new generation of measurements. For the electron electric dipole moment, new ACME measurements with an electron in a ThO molecule have achieved the longer coherence time, higher flux and more efficient quantum state detection needed to also increase the sensitivity to BSM CP violation that may be missing from the SM.
