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, is one of the major event reconstruction paradigms used 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. 

Xiangpan Ji received his Ph.D. in physics from Nankai University in 2014. He was a Chung-Yao Chao postdoctoral fellow from 2015 to 2017 at Tsinghua University and then joined Brookhaven National Laboratory as a postdoctoral research associate in 2018. Xiangpan Ji has been working on Daya Bay and PROSCPECT reactor neutrino experiments and has made important contributions. He now focuses on the MicroBooNE neutrino experiment. As one of the major contributors, they obtained the most sensitivity LEE research in MicroBooNE.
