I suggest you to read my answer here for a quick look into exotic hadrons. These particles mostly(at least so far) are very unstable appears for a short time and decay into another particles, hadrons and mesons. Hadrons made of 3 quarks and mesons one quark and its anti-matter. These unstable particles(resonances) have a quark content based on initial and ...

In Scientific American, they said it was this specific grouping as illustrated, though with arbitrary coloring. It briefly stated how it must involve which quarks based on decay channels. I lost my hardcopy of the magazine so I can't easily look upmthe quotation now. I think it was not as you describe though... Yea, it's in Wikipedia now. In July ...

A pentaquark is a particle made of five quarks. "Penta" means 'five' in Greek. Technically it could be made of any combination of quarks/antiquarks, though subject to some restrictions - see below. Quarks are bound by the strong force. In the same way as the electromagnetic force sees the (electric) charge of particles and causes interactions only within ...

if it's a singlet then its spin is 0. the SU(3) rep 3x3x3x3x3' (dim=243) decomposes into a bunch of 1,8,10,27, and 35 multiplets with many possible spins (mathematically speaking at least)

I can't answer your question per se, but I hope I can offer something that's of some use: See this report: "The LHCb team is confident that the particles are indeed pentaquarks that comprise two up quarks, one down quark, one charm quark and one anticharm quark. "Benefitting from the large data set provided by the LHC, and the excellent precision of our ...

There's 2 types of particles that quarks can form, Baryons and Mesons. List of Baryons and List of Mesons All of these, except for the Proton are unstable. The Neutron is unstable on it's own but it's stable when bound to Protons in an atomic Nucleus. A Baryon is 3 quarks and a Meson is 2 quarks, so that limits the number of combinations. Description ...
