The Extra Low ENergy Antiproton ring (ELENA) is now in the commissioning phase.
Only a few direct measurements have been performed so far to test this conjecture.
This high-precision measurement was achieved by comparing the cyclotron frequencies of antiprotons and negatively charged hydrogen ions in a Penning trap.
Claude Amsler looks at some of the studies over the years at CERN.
The Alpha Magnetic Spectrometer (AMS) on the International Space Station (ISS) has new results on energetic cosmic-ray electrons and positrons, based on analysis of the first 41 billion events.
Antiprotons returned to CERN’s Antiproton Decelerator (AD) on 5 August and experiments have been receiving beams since mid-September, following an intensive consolidation programme during the first...
ALPHAfound it to be compatible with zero to eight decimal places.
A German/Japanese collaboration working at the University of Mainz has performed the first direct high-precision measurement of the magnetic moment of the proton – which is by far the most accurate ...
The ASACUSA collaboration reports the unambiguous detection of antihydrogen atoms 2.7 m downstream from their production.
A report from a meeting in Bern on the interactions of antimatter with gravity.
