This note presents the status of the measurement of electron neutrinos from the Fermilab Booster Neutrino Beamline (BNB) with the MicroBooNE experiment. The analysis is aimed at investigating the nature of the low energy excess of electromagnetic activity observed by the MiniBooNE experiment. The νe event selection relies on topological and calorimetric information to characterise particles produced in these interactions, leveraging the Pandora multi-algorithm reconstruction framework as well as custom particle identification and pattern recognition tools. Results presented in this note use 5.88 × 1020 protons on target of data collected between 2015 and 2018. These include the performance of particle identification tools for µ/p and e/γ separation, along with electromagnetic shower calibration with the largest sample of π 0 events measured on argon. Progress towards the completion of this analysis is shown through the measurement of high-energy charged-current νe interactions and their kinematic distributions using both inclusive (1eX) and exclusive (1e0p0π and 1eNp0π) channels. Measurements of charged-current νµ interactions aimed at constraining flux and cross-section systematic uncertainties are also shown. We present the analysis’ preliminary sensitivity of an electron-like signal hypothesis to the MiniBooNE excess which includes flux, cross-section, and detector systematic uncertainties.
