alevy writes to mention that scientists at Fermilab have detected a new, completely untheorized particle. Seems like Fermi has been a hotbed of activity lately with the discovery of a new single top quark and narrowing the gap twice on the Higgs Boson particle. "The Y(4140) particle is the newest member of a family of particles of similar unusual characteristics observed in the last several years by experimenters at Fermilab's Tevatron as well as at KEK and the SLAC lab, which operates at Stanford through a partnership with the U.S. Department of Energy. 'We congratulate CDF on the first evidence for a new unexpected Y state that decays to J/psi and phi,' said Japanese physicist Masanori Yamauchi, a KEK spokesperson. 'This state may be related to the Y(3940) state discovered by Belle and might be another example of an exotic hadron containing charm quarks. We will try to confirm this state in our own Belle data.'"
