Atmospheric Muon Background Suppression for KM3NeT(pdf)

KM3NeT is a future European deep-sea research infrastructure hosting new generation neutrino telescopes with a volume of several cubic kilometers located at the bottom of the Mediterranean Sea. There are two telescopes under development by the KM3NeT collaboration, ARCA focusing on high energy events (TeV energies) and ORCA focusing on lower energy events (GeV energies). In my current work I have been involved in the analysis of Monte Carlo simulated events for ARCA in order to find a way to identify and efficiently isolate the Atmospheric Muon Background from the Charge Current Muon Neutrino (Signal) events. A new method is being developed to reliably identify events with the interaction vertex inside the detector in order to suppress the background from atmospheric muon events. So far a rejection of 99.999% of the incoming atmospheric muons (background) is achieved.
