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.
Claude Amsler looks at some of the studies over the years at CERN.
This high-precision measurement was achieved by comparing the cyclotron frequencies of antiprotons and negatively charged hydrogen ions in a Penning trap.
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.
