Speakers: Dr William Bertsche

Antimatter, first predicted by Paul Dirac in 1931 and now routinely created and observed in the laboratory, is the centre of a major conundrum in physics: present models predicts that antimatter should have been created in equal quantities to matter at the formation of the universe; so how do we explain its scarcity in the world we live in today?
The ALPHA experiment at CERN addresses this question by making measurements of the properties of the antihydrogen atom, an antimatter version of the hydrogen.
Any minute difference found between antihydrogen and hydrogen would be a significant clue into this mystery.
ALPHA has recently achieved trapping antihydrogen, and for the first time, begun to experimentally probe its properties.
