IceCube filters towards an unified all-flavor neutrino sample

IceCube measured an astrophysical neutrino flux in the 100 TeV to PeV range at the level of 10^-8 GeV cm^-2s^-1sr^-1 per flavor with three years of data collected between 2010 and 2012. The data is consistent with isotropic neutrino arrival directions. In order to enhance the probability to detect the sources of these neutrinos, the data sample can still be optimized by taking all possible detection channels into account and by optimizing various steps of the data processing chain. The goal is to create an unified all-flavor neutrino sample that selects both track- and cascade-like events originating from the whole sky. As a first step, we investigated a possible increase in the efficiency of selecting (neutrino-induced) muon events at the South Pole when introducing a new clustering algorithm earlier into the processing chain. This algorithm was developed to find and split coincident events and to remove hits caused by noise. The results of this study are going to be presented in this talk.
