Measurement of Neutral-Current π0π0 Cross Section in MicroBooNE using Wire-Cell Reconstruction

UNSPECIFIED (2022) Measurement of Neutral-Current π0π0 Cross Section in MicroBooNE using Wire-Cell Reconstruction. Other. UNSPECIFIED.

Abstract

This note presents the extraction of flux-averaged total and differential neutral-current π0 cross section measurements, based on the Wiener-SVD unfolding method, using the MicroBooNE Liquid Argon Time Projection Chamber (LArTPC) and the Wire-Cell reconstruction paradigm. This measurement is critical for single-photon searches as neutral-current pion production represents one of the largest sources of background. We report the results for an exposure corresponding to 5.327 × 1019 protons-on-target (POT).
