Exotic antimatter particle produced by LHC
by James Lloyd, Cosmos Online, Tuesday, 29 March 2011 SHROPSHIRE: Using data from the Large Hadron Collider (LHC) experiment, a team of scientists has observed new behaviour of an exotic ‘B meson’ particle. The discovery of this new particle decay mode could help to shed light on one of the most puzzling unknowns in physics. When the universe was formed from the Big Bang 14 billion years ago, matter and antimatter were created in equal quantities. Today, however, we find ourselves in a universe composed almost entirely of matter. The apparent disappearance of antimatter could be explained if scientists discover differences in the way matter and antimatter decay.
