LHC detects asymmetry in particle’s decay

While interesting, strange B meson's preference for matter over antimatter isn't enough to explain universe's existence

A short-lived subatomic particle preferentially decays into matter rather than antimatter, researchers from the Large Hadron Collider report April 23 at arXiv.org. The strange B meson is only the fourth particle known to exhibit this behavior, providing physicists with a new avenue for figuring out why matter predominates over antimatter in the universe.
