A new measurement of the electron magnetic moment from Physics and Astronomy's Board of Trustees Professor, Gerald Gabrielse and his research group at Northwestern University’s Center for Fundamental Physics has delivered the most precise measurement of a property of any elementary particle. At the part per trillion level, the measurement improves the previous result – a 15-year-old discovery also made by a Gabrielse-led team – by a factor of two.
Physics, the publication tracking groundbreaking results in the field, called the Northwestern group’s work “a triumph for fundamental physics.
At present, the Standard Model of Particle Physics is the world’s best description of physical reality. Gabrielse acknowledges the Standard Model is a battle-tested theory capable of predicting nearly everything humans can measure and test on Earth. When it comes to the universe, however, the Standard Model falls short and fails to account for basic features.
“The quest we’re on is to make the most precise measurements of properties of elementary particles to probe the Standard Model’s most precise prediction,” Gabrielse said.
