High-performance Generic Neutrino Detection in MicroBooNE

MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) operating near the surface. The main physics goals of this experiment include studying the nature of the low-energy excess events observed in MiniBooNE and measuring the neutrino-Argon interaction cross section. With a large drift time, the cosmic rays are a major background to the neutrino interaction events. In this talk, I will describe a series of novel event reconstruction techniques that are used to reject cosmic muon backgrounds. With these tools, high-performance neutrino detection is achieved with a signal-to-background ratio above four while maintaining detection efficiency above 80\% for charge-current $\nu_\mu$ interaction events.
