Abstract:
'Astrophysical tau neutrinos can cause double pulse waveform signals in IceCube photon sensors. A previous 8-year analysis has found three tau neutrino candidates and the most promising one which is located very near to the dust layer in the detector. We will present a posteriori analysis on this event using a new ice model treatment with continuously varying parameters to do targeted volume re-simulation for tau neutrino and other background neutrino ensembles, which aims to explore the impact of different ice models on the expected signal and background statistics.'
