N2 - This note describes and presents preliminary results for the MicroBooNE analysis being developed to search for neutrino-induced neutral current single photon events in the MicroBooNE detector. The analysis currently assumes neutrino neutral current ∆ production followed by ∆ radiative decay on argon (NC ∆ → N γ) as the “signal model”; event reconstruction and selection have been developed and are being optimized in order to reduce cosmogenic and other beam-related backgrounds explicit to the NC ∆ → N γ process. This note presents the current status of event reconstruction, selection, optimization and validation checks for the early stages of analysis on external (cosmogenic background) events. Also presented are the projected sensitivities for testing the standard model predicted rate for the NC ∆ → N γ process and for testing the interpretation of the previously observed MiniBooNE low energy excess as NC ∆ → N γ events.
