%0 Journal Article %T Towards an Improved Test of the Standard Model¡¯s Most Precise Prediction %J Atoms | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/atoms7020045 %X The electron and positron magnetic moments are the most precise prediction of the standard model of particle physics. The most accurate measurement of a property of an elementary particle has been made to test this result. A new experimental method is now being employed in an attempt to improve the measurement accuracy by an order of magnitude. Positrons from a ¡°student source¡± now suffice for the experiment. Progress toward a new measurement is summarized. View Full-Tex %U https://www.mdpi.com/2218-2004/7/2/45
