TL;DR: This work demonstrates the production of antihydrogen atoms at very low energy by mixing trapped antiprotons and positrons in a cryogenic environment and detects the neutral anti-atoms directly when they escape the trap and annihilate, producing a characteristic signature in an imaging particle detector.

TL;DR: Antihydrogen has been created, trapped and stored for 1,000 years and the improved holding time means that we now have access to the ground state of antimatter, long enough to test whether matter and antimatter obey the same physical laws as mentioned in this paper.

TL;DR: Spectroscopy of a pure antimatter atom is reported, demonstrating resonant quantum transitions inAntihydrogen, and the direct detection of the annihilation of antihydrogen atoms ejected by the microwaves is described.

TL;DR: The application of evaporative cooling to clouds of trapped antiprotons, resulting in plasmas with measured temperature as low as 9 K, opens up new possibilities for cooling of trapped ions and is of particular interest in antiproton physics.

TL;DR: The achieved positron accumulation rate in the high field cryogenic trap is more than one and a half orders of magnitude higher than the previous most efficient UHV compatible scheme.
