No guaranteed neutrino astronomy without (enough) double bang tau and downward HESE muon tracks: An update version

TL;DR

This paper discusses the challenges in neutrino astronomy, highlighting how atmospheric charm noise and tau neutrino scarcity affect data interpretation and the importance of double bang tau and downward HESE muon tracks.

Contribution

It provides an updated analysis emphasizing the dominance of charm noise and the significance of specific neutrino detection signatures in IceCube data.

Findings

Charm noise dominates the neutrino data.

Tau neutrino scarcity affects astronomy signals.

Double bang tau and downward HESE muon tracks are crucial.

Abstract

IceCube Neutrino Astronomy is considered. The tau neutrino flavor paucity and the asymmetry for the tracks suggest a dominant atmospheric charm noise. The correlated cascades and tracks asymmetry with relevant statistics enforce the charm noise dominance in the data. The charm signal may explain at once the absence of correlation for the tracks data with the galactic plane and with known brightest gamma sources.
