UNSPECIFIED (2024) Progress Towards An Expanded Search For Neutral-Current Delta Radiative Decays In MicroBooNE. Other. UNSPECIFIED.

Abstract

In this note, we present progress toward an expanded search for neutral current Delta radiative decays (NC Δ→NγΔ→Nγ) in MicroBooNE. We present sensitivities for several tests of the MiniBooNE Low Energy Excess (LEE) under NC Δ→NγΔ→Nγ scaling hypotheses, with significantly enhanced sensitivity relative to previous tests. These selections can also be used for additional single photon searches in the future, including searches which target more specific hadronic final states and particular regions of shower kinematic phase space.
