Features in the Standard Model diphoton background

High Energy Physics - Phenomenology 2016-08-03 v2 High Energy Physics - Experiment

Abstract

We argue that electromagnetic decays of energetic unflavoured neutral mesons, notably η\eta, mis-identified as single photons due to granularity of the electromagnetic calorimeter might create bump-like features in the diphoton invariant mass spectrum at different energies, including 750 GeV. We discuss what kind of additional analysis can exclude or confirm this hypothesis.
