The SuperB project involves the construction underground of a new asymmetric high-luminosity electron–positron collider.
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 ...
Read article 'Why antihydrogen and antimatter are different'
As Dirac realized, there’s more to antimatter than antihydrogen.
Read article 'ASACUSA moves towards new antihydrogen experiments'
Recently, the Japanese–European group made the first steps towards producing a low-velocity antihydrogen beam.
Read article 'Keeping antihydrogen: the ALPHA trap'
Jeffrey Hangst describes a new antihydrogen experiment at CERN.
Read article 'ATRAP tests new way to make antihydrogen'
The new method consists of exciting caesium atoms from an oven with two lasers, and then introducing the caesium into a positron trap.
Read article 'ATRAP catches speed of antihydrogen'
This is an important step towards the goal of producing antihydrogen atoms cold enough – that is, slow enough – for precision spectroscopy.
