Antiprotons to hit the road

“This project might lead to the democratisation of the use of antimatter,” says project leader Alexandre Obertelli of TU Darmstadt.

Experiment of the moment

The BASE collaboration at CERN has measured the antiproton magnetic moment with extraordinary precision.

Illuminating antimatter

The ALPHA collaboration has made seminal measurements of antihydrogen’s spectral structure in a bid to test nature’s fundamental symmetries.

HAWC clarifies cosmic positron excess

New measurements by the High-Altitude Water Cherenkov (HAWC) experiment hints at a more exotic origin of the positron excess.

Hyperfine structure: from hydrogen to antihydrogen

The ASACUSA experiment at CERN’s Antiproton Decelerator published the most precise in-beam measurement of the hydrogen ground-state hyperfine splitting.

GBAR falls into place

Located in CERN's Antiproton Decelerator hall, GBAR is specifically designed to measure the effect of gravity on antihydrogen atoms.

BASE boosts precision of antiproton magnetic moment

The measurement shows that the magnetic g-factors are identical within 0.8 parts per million.

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...
