This antimatter and hypernucleic atom consists of an antiproton, two antineutrons, and an antilambda particle. A lambda particle is a hyperon containing one strange quark, while the antilambda is ...

Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported ...

The findings, which are published in Nature, confirm the capabilities of anti-atom spectroscopy and bring the development of ultra-sensitive tests of antimatter one step closer, and with it a ...

Experiments at CERN's Antimatter Factory test fundamental principles ... by measuring the frequencies of transitions in the anti-atom using laser light or microwaves. If the results match those ...
