CERN’s ALPHA experiment measures charge of antihydrogen

Geneva, 3 June 2014. In a paper published in the journal Nature Communications today, the ALPHA experiment at CERN1's Antiproton Decelerator (AD) reports a measurement of the electric charge of antihydrogen atoms, finding it to be compatible with zero to eight decimal places. Although this result comes as no surprise, since hydrogen atoms are electrically neutral, it is the first time that the charge of an antiatom has been measured to high precision.
