Coincident Muon Analysis Between the DM-Ice17 and IceCube Detectors

DM-Ice17 is a direct detection dark matter experiment with two detectors located within the volume of the IceCube Neutrino Observatory at the South Pole. We report the use of muons coincident between DM-Ice17 and IceCube to verify muon identification in DM-Ice17 and provide a novel calibration technique for IceCube. Such events are unique within the IceCube data sample because they are known to pass through each 2,309\,cm$^3$ DM-Ice17 crystal volume within IceCube's 1\,km$^3$ total volume. Different muon track reconstruction techniques are explored to optimize resolution by minimizing distance from DM-Ice17 and maximizing accuracy in angles of approach. Reconstructions are performed both on data and simulation. Results indicate a strong improvement in the reconstruction accuracy of low-energy events with the addition of DM-Ice17 information.
