ATLAS discovers its first new particle
[December 2011]
The ATLAS collaboration has announced the discovery of the 
b(3P), which is a bound state of a bottom quark and bottom antiquark (
). Bound states of a heavy quark and its antiquark are collectively called quarkonium. They are the QCD (Quantum Chromodynamics or strong force) analogues of the hydrogen atom, with each new particle corresponding to a different energy level.
