http://physicsweb.org/article/news/7/11/7New particle turns up in Japan
14 November 2003
The Belle collaboration at the KEK laboratory in Japan has discovered a new sub-atomic particle which it is calling the "X(3872)". The particle does not fit into any known particle scheme and theorists are speculating that it might be a hitherto unseen type of meson that contains four quarks
This people claims that is possible that they have discovered a particle made of 4 quarks, and I've read that there's also speculation about a particle called hexaquark, made of 6 quarks. Is there a limit to the number of quarks that can have a particle?
Would be surprising if someone in the future discovers the "dodecaquark"
