CERN announced that its ASACUSA experiment has produced the world's first-ever beam of antihydrogen atoms. Such beams will make possible a couple of tests that seek to answer one of the biggest questions in physics: Why is there more matter than antimatter?
"The ASACUSA experiment at CERN has succeeded for the first time in producing a beam of antihydrogen atoms. In a paper published today in Nature Communications, the ASACUSA collaboration reports the unambiguous detection of 80 antihydrogen atoms 2.7 metres downstream of their production, where the perturbing influence of the magnetic fields used initially to produce the antiatoms is small. This result is a significant step towards precise hyperfine spectroscopy of antihydrogen atoms." in CERN Press Office
