(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Make a very rough estimate of the probability that two high energy photons with an invariant mass of 126GeV are decay products of the Higgs. Use information found elsewhere (so I need to find this info preferably on the internet).

2. Relevant equations

3. The attempt at a solution

I'm not really sure what I need for my estimate! Would it work if I find the number of background events at 126GeV and the number of Higgs events then do Higgs / (Higgs + background) ? That sort of data is proving hard to find, so I suspect I should be looking for some other information... I did think the table on page 4 http://inspirehep.net/record/1257018/files/ICHEP2012_045.pdf here might be useful, if I knew how to interpret it.

I'd really appreciate any pointers on where I might find data on the number of events, or whether that's completely the wrong approach. Thanks for any help! :)

Edit: I could maybe very crudely read the values off this graph, I think it's about 400 Higgs events in the 5000 total events? But I could be horribly misinterpreting the meaning of the graph.
