Read article 'ALPHA collaboration gets antihydrogen in the trap'
Do matter and antimatter obey the same laws of physics? One intriguing way to test this would be to compare the spectra of hydrogen and its antimatter twin: antihydrogen.
Read article 'Antihydrogen scoops award for breakthroughs'
Both ALPHA and ASACUSA aim to measure precisely the spectrum of antihydrogen and compare it with that of hydrogen. Any small difference would cast light on the imbalance between matter and antimatter ...
