Search for antimatter in space on the International Space Station ALPHA.
Abstract
The apparent absence of antimatter (antihelium, anticarbon, etc.) in the universe is one of the great puzzles in particle physics. Theories (based on CP-violation, baryon violation, the standard model, and grand unification) which predict either the existence of antimatter in segregated domains or the total absence of antimatter are highly speculative. These theories have no firm foundation in experimental data. The author proposes a search for antimatter in cosmic radiation, a 104 to 105 improvement over existing measurements, which is sufficiently sensitive to address these particle physics issues.
