- Abstract summary: We search for neutrino emission using machine learning techniques applied to ten years of data from the IceCube Neutrino Observatory.
We identify neutrino emission from the Galactic plane at the 4.5$sigma$ level of significance, by comparing diffuse emission models to a background-only hypothesis.
The signal is consistent with modeled diffuse emission from the Galactic plane, but could also arise from a population of unresolved point sources.

- Abstract: The origin of high-energy cosmic rays, atomic nuclei that continuously impact
Earth's atmosphere, has been a mystery for over a century. Due to deflection in
interstellar magnetic fields, cosmic rays from the Milky Way arrive at Earth
from random directions. However, near their sources and during propagation,
cosmic rays interact with matter and produce high-energy neutrinos. We search
for neutrino emission using machine learning techniques applied to ten years of
data from the IceCube Neutrino Observatory. We identify neutrino emission from
the Galactic plane at the 4.5$\sigma$ level of significance, by comparing
diffuse emission models to a background-only hypothesis. The signal is
consistent with modeled diffuse emission from the Galactic plane, but could
also arise from a population of unresolved point sources.

neutrino-neutrino coherent scattering can give rise to nontrivial quantum entanglement among neutrinos.
We observe that the entanglement induced by the coupling leads to strong delocalization in phase-space with largely non-Gaussian quantum fluctuations.
The link between the neutrino entanglement and quantum fluctuations is illustrated using the one- and two-neutrino entropy.

oscillations [0.0]
We find an intriguing connection between the entropy of entanglement of individual neutrinos with the rest of the ensemble.
For various types of neutrino spectra, we demonstrate that the entanglement entropy is highest for the neutrinos whose locations in the energy spectrum are closest to the spectral split(s)
This trend demonstrates that the quantum entanglement is strongest among the neutrinos that are close to these splits, a behavior that seems to persist even as the size of the many-body system is increased.
