Study of π0 Events in MicroBooNE and Applications to the Deep Learning LEE Search

UNSPECIFIED (2020) Study of π0 Events in MicroBooNE and Applications to the Deep Learning LEE Search. Other. UNSPECIFIED.

Abstract

We present a selection of events containing π 0 particles in the MicroBooNE detector. These events are used to understand the important pi0 background in the deep learning (DL) based electron low energy excess (e-LEE) analysis. The selection uses a new shower reconstruction algorithm based on tools in the DL reconstruction chain. We present the efficiency and energy resolution of the selection. We also present the planned use of these events in energy calibration using the reconstructed π 0 mass.
