Re: CERN confirms probable tetraquark particle

P.S. Is this indeed confirmed to be a tetraquark? Previously discovered particles like Zc(3900) are also suspected to be tetraquarks, but haven't been confirmed to be such as of yet(?)
The particle is confirmed (a couple thousand observations), but I don't think they're completely certain that it's a tetraquark, but they indicate that an entanglement of two paired-quarks doesn't work out to the right mass, making a tetraquark the best explanation.

I'm still pushing for a word that describes a group of quarks, which would obviously be a groupon. It's trendy!
