Physicists at the European Organization for Nuclear Research (CERN) have announced the discovery of a new particle, the excited state of the the neutral Xi_b. This particle consists of up, strange, and bottom quarks and was predicted to exist from quantum chromodynamics, one of the most successful theories ever developed.
If you are so inclined, the paper submitted to Physical Review Letters can be found here.
