Hello, I'm currently in my last year of high school and I'm doing a project about the higgs particle decaying to two photons. I am using HYPATIA to analyse ATLAS events. When a higgs boson decays into two photons, you can see activity in the electromagnetic calorimeter without seeing a track pointing to it in the tracker (because photons don't have charge). To mark an event as a Higgs particle decaying into two photons requires some criteria. Can you mark an event as a higgs particle decaying into two photons if there are also neutrino's? Is it possible that a higgs particle decays into two photons and that the neutrino's are just some kind of noise? I'm very sorry if I'm being vague, but I'm not really good in explaining my question. Thanks in advance!
