Title: First observation of low energy electron neutrinos in a liquid argon time projection chamber

Liquid argon time projection chambers (LArTPCs) produce remarkable fidelity in the observation of neutrino interactions. Here, the superior capabilities of such detectors to reconstruct the spatial and calorimetric information of neutrino events have made them the detectors of choice in a number of experiments, specifically those looking to observe electron neutrino ($$\nu_e$$) appearance. The LArTPC promises excellent background rejection capabilities, especially in this "golden" channel for both short and long baseline neutrino oscillation experiments. We present the first experimental observation of electron neutrinos and anti-neutrinos in the ArgoNeut LArTPC, in the energy range relevant to DUNE and the Fermilab Short Baseline Neutrino Program. Additionally, we present a demonstration of separation of electrons from gammas using neutrino data.
