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.
New measurements by the High-Altitude Water Cherenkov (HAWC) experiment hints at a more exotic origin of the positron excess.
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.
The measurement shows that the magnetic g-factors are identical within 0.8 parts per million.
The ALPHA collaboration has reported the first ever measurement of the optical spectrum of an antimatter atom.
Measuring the effect of gravity on antimatter is a long-standing story. Now we are in a position to test Einstein’s equivalence principle with antimatter by directly measuring the free fall of antia...
