## Abstract

MicroBooNE (the Micro Booster Neutrino Experiment) is a short-baseline neutrino experiment based on the technology of a liquid-argon time-projection chamber (LArTPC), and has recently completed its first year of data-taking in the Fermilab Booster Neutrino Beam. It aims to address the anomalous excess of events with an electromagnetic final state in MiniBooNE, to measure neutrino-argon interaction cross sections, and to provide relevant R\&D for the future LArTPC experiments, such as DUNE. In these proceedings, we present the first reconstructed energy spectrum of Michel electrons from cosmic muon decays, the first kinematic distributions of the candidate muon tracks from $\nu_{\mu}$-argon charged-current interactions, and a demonstration of an electromagnetic shower reconstruction from $\pi^0$s produced by $\nu_{\mu}$-argon charged-current interactions. The results demonstrate the first fully automated reconstruction and selection algorithms in a large LArTPC and serve as foundations for future measurements.
