Strong constraints on neutrino nonstandard interactions from TeV-scale $\nu_\mu$ disappearance at IceCube

IceCube Collaboration, M. Ackermann, J. Adams, J. A. Aguilar et autres

We report a search for nonstandard neutrino interactions (NSI) using eight years of TeV-scale atmospheric muon neutrino data from the IceCube Neutrino Observatory. By reconstructing incident energies and zenith angles for atmospheric neutrino events, this analysis presents unified confidence intervals for the …

Search for Spatial Correlations of Neutrinos with Ultra-high-energy Cosmic Rays

M. André, M. Ardid, J.-J. Aubert, B. Baret et autres

For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to correlate UHECRs with high-energy neutrinos, since neutrinos are a direct probe of hadronic interactions of cosmic …

Search for Quantum Gravity Using Astrophysical Neutrino Flavour with IceCube

R. Abbasi, M. Ackermann, J. Adams, J. A. Aguilar et autres

Along their long propagation from production to detection, neutrino states undergo quantum interference which converts their types, or flavours. High-energy astrophysical neutrinos, first observed by the IceCube Neutrino Observatory, are known to propagate unperturbed over a billion light years in vacuum. These …

Cosmic ray spectrum from 250 TeV to 10 PeV using IceTop

M. G. Aartsen, M. Ackermann, J. Adams, J. A. Aguilar et autres

We report here an extension of the measurement of the all-particle cosmic-ray spectrum with IceTop to lower energy. The new measurement gives full coverage of the knee region of the spectrum and reduces the gap in energy between previous IceTop and direct …
