Search for an Anomalous Excess of Inclusive Charged-Current Electron Neutrino Interactions in the MicroBooNE Experiment using Wire-Cell Reconstruction

by Xiangpan Ji (BNL)


The MicroBooNE experiment was designed primarily to address the anomalous low-energy excess (LEE) in electron neutrino candidates observed by the MiniBooNE experiment and to resolve if the excess is due to neutrino-produced electrons or photons. Located on the same Booster Neutrino Beamline at Fermi National Accelerator Laboratory as the MiniBooNE detector, the MicroBooNE Liquid Argon Time Projection Chamber utilizes superb imaging and calorimetry capabilities to differentiate electrons from photons which is key to resolving the MiniBooNE excess. A tomographic three-dimensional image reconstruction algorithm, Wire-Cell, was developed at BNL  as one of the major event reconstruction paradigms deployed in MicroBooNE. In this talk, I will report the latest LEE search results of MicroBooNE based on data taken from February 2016 to July 2018 in inclusive charged-current electron neutrino-induced interactions using data analysis techniques based on the Wire-Cell reconstruction paradigm.
