Search for non-pointing photons in the diphoton and $E_T^{miss}$ final state in $\sqrt{s}=7~{TeV}$ 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...
