“…These triggers are based on temporal and/or spatial coincidences that could arise from the Cherenkov photons emitted by a charged particle in the detector. Most triggers rely on the concept of Hard Local Coincidence (HLC), a flag given to a DOM when it registers light within 1 µs of its neighbor or next-tonearest neighbor on the same string [34].…”

“…The best constraint to date comes from survival of atmospheric muon neutrinos observed by the former IceCube detector AMANDA-II in the energy range 100 GeV to 10 TeV [45], which searched for a generic LIV in the neutrino sector [46] and achieved (∆c/c) IJ ≤ 2.8 × 10 −27 at 90% confidence level assuming maximal mixing for some of the combinations I, J. Given that IceCube does not distinguish neutrinos from antineutrinos, the same constraint applies to the corresponding antiparticles.…”

Abstract.Recently there has been a renewed activity in the physics of violations of Lorentz invariance in the neutrino sector. Flavor dependent Lorentz violation, which generically changes the pattern of neutrino oscillations, is extremely tightly constrained by oscillation experiments. Flavor independent Lorentz violation, which does not introduce new oscillation phenomena, is much more weakly constrained with constraints coming from time of flight and anomalous threshold analyses. We use a simplified rotationally invariant model to investigate the effects of finite baselines and energy dependent dispersion on anomalous reaction rates in long baseline experiments and show numerically that anomalous reactions do not necessarily cut off the spectrum quite as sharply as currently assumed. We also present a revised analysis of how anomalous reactions can be used to cast constraints from the observed atmospheric high energy neutrinos and the expected cosmogenic ones.

“…Based on the HLC hits recorded by the DOMs, event triggers set certain criteria for reading out all signal recorded by DOMs, including non-HLC pulses, for further processing. Different event trigger definitions are used in the IceCube online systems [29], and the events used in the Kaggle competition satisfy at least one of them.…”

During the public Kaggle competition “IceCube – Neutrinos in Deep Ice”, thousands of reconstruction algorithms were created and submitted, aiming to estimate the direction of neutrino events recorded by the IceCube detector. Here we describe in detail the three ultimate best, award-winning solutions. The data handling, architecture, and training process of each of these machine learning models is laid out, followed up by an in-depth comparison of the performance on the Kaggle datatset. We show that on cascade events in IceCube above 10 TeV, the best Kaggle solution is able to achieve an angular resolution of better than 5$$^{\circ }$$ ∘ , and for tracks correspondingly better than 0.5$$^{\circ }$$ ∘ . These results indicate that the Kaggle solutions perform at a level comparable to the current state-of-the-art in the field, and that they may even be able to outperform existing reconstruction resolutions for certain types of events.
