反物质的观测与相互作用探索

An Exploration of the Antimatter and Interactions therein

在我们所处的世界,正反物质的不对称性是物理学领域的未解之谜。反物质研究是国际上高能物理领域的热点,有关反物质研究的进展对我们认识物质结构有着重要的启示。

The article briefs the history and the recent development of antimatter research, with an emphasis on the recent observations from relativistic heavy ion collision, especially on the first measurement of antiproton pair interaction. Also mentioned are the studies on antihydrogen atom and space exploration. The implications of these studies are discussed.
