CERN confirms probable tetraquark particle

They've confirmed the particle, called Z(4430), and have seen thousands of them, and think it is made up of two quarks and two anti-quarks, showing that four-quark particles exist, and perhaps occur in neutron stars.

New Scientist link

Any suggestions for a better name than Z(4430)?

I think they should call it a 'groupon'.
