Exciting discoveries in particle physics are one of those things that it can be easy to get blase about. Some people get caught up in the obvious excitement, while others yawn: \u201cOh, you found the Higgs Boson, just like Higgs predicted. Call me when you have something new.\u201d Well, if you\u2019re in category B, prepare to yawn while the rest of us break out champagne, because it looks like we\u2019ve finally found the glueball.\u00a0<\/a><\/p>\n

The glueball has got to be one of the oddest particles to fall out of the Standard Model. It\u2019s not a fundamental particle, but its makeup contains no quarks\u2013 those itty bits that make up protons and neutrons\u2013 nor any leptons like electrons or muons. No, the glueball is a hadron made entirely of bosons: specifically, gluons, the force-carrying particles of the strong nuclear force. It\u2019s also been called gluonium or a gluon-ball, but glueball is more fun.<\/p>\n

Try and imagine a proton without any quarks. Remember that inside the proton there are three quarks, held together with force-carrying gluon particles. If you have zero quarks, but enough of those gluons tangled up in the right ways, and you get a tangible, if short lived particle. That\u2019s the glueball, a neutral particle that will decay almost immediatly in to Pions. It works because gluons have \u2018colour charge\u2019\u2013 the strong nuclear force\u2019s answer to electric charge.<\/p>\n

It\u2019s also one of those things that will probably never be seen in nature: odds are, even in the hottest collisions, you\u2019re going to get a quark or two mixed up with your gluon soup. That\u2019s okay; the gluonic state is what we\u2019ve been looking for. As long as the particle is mostly gluons, and behaves as the Standard Model predicts it should, physicists are inclined to call it good enough. The latest candidate to hit \u201cgood enough\u201d is X(2370), which fell out of a collision in the Beijing Electron\u2013Positron Collider II (BEPC II), as detected by the Beijing Spectrometer III (BES III). The paper hit ArXiv<\/a> at the end of July. It\u2019s taken the collaboration this long to make sure of what they were looking at, as they sorted through the terabytes of data an instrument like this generates.<\/p>\n

Is this likely to affect you in any way? No. It confirms what we already thought we knew about the universe, and the particle itself is too short-lived to ever exist outside of some very extreme\u2013 mostly man-made\u2013 environments. On the other hand, it\u2019s an excuse to celebrate scientific discovery, and we\u2019ll take any of those we can, just like when the Muon Magnetic Moment measured in<\/a> at the expected value, or neutrinos transmuted elements<\/a> in exactly the way the models said they would. Besides, if we\u2019re really lucky this result will turn out not to be a glueball, but something new and interesting. Then even the most jaded nerds will have reason to celebrate.<\/p>\n
