Study of separating cosmic ray muon bundles from neutrino induced single muons

The IceCube Neutrino Observatory, a cubic-kilometer detector located at the geographic south pole detects potential neutrino candidates of astrophysical origin and sends alerts to the multi-messenger community for rapid follow-up observation. Cosmic ray induced muons are the largest background in the detection of astrophysical neutrinos from the southern hemisphere. A large number of muons are produced from cosmic ray air showers compared to single muons. Separating the muon bundles from neutrino induced single muons is crucial the detection process. Muons in the bundles travel with a slight offset as they are produced in different interactions in the air shower. Early pulses will be observed in the cosmic ray induced muons than for the neutrino induced single muons. We will show this time offset signature can be used to separate the cosmic ray induced bundles from the signal muons.
