Anomalous di-photon resonance at 750 GeV

[Mark R]

Would someone be good enough to translate the above into English, and provide an explanation of its significance.

(As you might guess from the long words, I've read the various articles in things like the Huff Po and Daily Fail, but I'm looking for something a bit more substantial).

A couple of high-energy light packets were produced by the decay of something or somethings. That something, if it is just a single thing, is heavier than any known particle. (GeV, Giga Electron-Volts is a unit of energy, and thus a small unit of mass too.)

I saw an article about the various things they're looking for at the LHC now, but I can't find it. This energy actually seems too low to be a supersymmetric particle. My best guess: another Higgs? (There could be up to 3, I think.)

Or it could be nothing.

You know what?

That is one damnfine explanation for a numbskull like me. This is the first applied/basic physics hardcore-jargon topic on AT that I was able to understand, and be fascinated by, instantly! Kudos!


Now, I shall continue to not understand the rest, and sip my beer in peace.

Do a google image search for Feynman diagrams & diphotons - and it'll give you an idea of what's going on. Now, in the colliders, there are a lot of different particles that are decaying, and you don't know exactly what you're going to get that decays - you can't see them directly, but you see how much energy they had from the energy of the photons released during their decay. The two photons don't necessarily have to be the exact same energy. When you sum the energies of the two photons, and plot the sum for a large number of decays, you'll get a lot of peaks centered around certain amounts of energy. When you suddenly start seeing a peak around, say, 750Gev, you'd say you had a resonance at 750GeV.

I think. I might be having a brain fart. I know this is done in the CMS detector, except it's the muon energies that are added.

Agreed!
