First beam of antihydrogen atoms

ASACUSA at CERN, Antiproton Decelerator [AD], a Japanese-European collaboration working on antihydrogen production for the CPT symmetry test, has unambiguously detected an antihydrogen beam 2.7 meters downstream from the production region, for the first time. This is an important milestone towards high precision tests of the CPT symmetry via antihydrogen spectroscopy.

It is well-known that matter and antimatter are always created in equal amounts in laboratory experiments. It is …
