Physicists Trap Single Antimatter Particle for Precision Study
Tap title to read story
Physicists have suspended a single positron in mid‑air and cooled it to its lowest energy state. The experiment, detailed in Physical Review Letters on twenty‑first October, will allow researchers to measure the positron’s magnetic moment with unprecedented precision. The team hopes to detect subtle differences between matter and antimatter that could illuminate why the universe is dominated by matter. The work was led by Gerald Gabrielse of Northwestern University and supported by CERN and Heinrich Heine University.
