Working at CERN’s Antiproton Decelerator, the international BASE team has set the first laboratory limits on the interaction between antimatter and dark-matter axions
ALPHA-g and GBAR have begun campaigns to check whether antimatter falls under gravity at the same rate as matter.
The collaboration has reported the first measurement of the Lyman-alpha transition.
The 13th Low Energy Antiproton Physics (LEAP) conference was held from 12–16 March at the Sorbonne.
Measurements of the hydrogen’s spectral structure agree with theoretical predictions to a few parts in 1015. Researchers have long sought to match this precision for antihydrogen.
“This project might lead to the democratisation of the use of antimatter,” says project leader Alexandre Obertelli of TU Darmstadt.
The BASE collaboration at CERN has measured the antiproton magnetic moment with extraordinary precision.
The ALPHA collaboration has made seminal measurements of antihydrogen’s spectral structure in a bid to test nature’s fundamental symmetries.
The ASACUSA experiment at CERN’s Antiproton Decelerator published the most precise in-beam measurement of the hydrogen ground-state hyperfine splitting.
Located in CERN's Antiproton Decelerator hall, GBAR is specifically designed to measure the effect of gravity on antihydrogen atoms.
