Search for nonpointing photons in the diphoton and E[miss over T] final state in √s=7 TeV proton-proton collisions using the ATLAS detector
A search has been performed for photons originating in the decay of a neutral long-lived particle, exploiting the capabilities of the ATLAS electromagnetic calorimeter to make precise measurements of the flight direction of photons, as well as the calorimeter’s excellent time resolution. The search...
