Radio Detection of UHE Cosmic Rays and Neutrinos off the Moon with Two 30 m Telescopes

Universe
Due to the Askaryan effect, radio emissions will be produced when ultra-high-energy (UHE) cosmic rays and neutrinos impact the lunar regolith. Many experiments have been proposed and performed to detect such radio emissions from the lunar regolith ...

Science with Neutrino Telescopes in Spain

Universe, 2022
The primary scientific goal of neutrino telescopes is the detection and study of cosmic neutrino signals. However, the range of physics topics that these instruments can tackle is exceedingly wide and diverse.

Neutrinos and the Universe

Journal of Physics: Conference Series, 2013
In this talk, I review the potential connection of neutrinos to the Physics of the Early Universe, in particular the r le of (sterile) neutrinos to leptogenesis/baryogenesis and the dark sector of the Universe. The possibility of CPT Violation among active neutrinos at early times and its role in leptogenesis/baryogenesis without sterile neutrinos is ...

Neutrino flavor relaxation or neutrino oscillations? [PDF]

Journal of Experimental and Theoretical Physics Letters, 2004
We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino

Search for Sterile Neutrino Mixing Using Three Years of Icecube Deepcore Data [PDF]

, 2017
We present a search for a light sterile neutrino using three years of atmospheric neutrino data from the DeepCore detector in the energy range of approximately 10–60 GeV. DeepCore is the low-energy subarray of the IceCube Neutrino Observatory.

Neutrino mass matrix with U(2) flavor symmetry and neutrino oscillations

, 1997
The three neutrino mass matrices in the $SU(5)\times U(2)$ model are studied focusing on the neutrino oscillation experiments. The atmospheric neutrino anomaly could be explained by the large $\nu_{\mu} - \nu_{\tau}$ oscillation.

Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Neutrino oscillations with the MINOS, MINOS+, T2K, and NOvA experiments

New Journal of Physics, 2016
This paper discusses recent results and near-term prospects of the long-baseline neutrino experiments MINOS, MINOS+, T2K and NOvA. The non-zero value of the third neutrino mixing angle θ _13 allows experimental analysis in a manner which explicitly ...

Neutrino amplitude decomposition: toward observing the atmospheric-solar wave interference

European Physical Journal C: Particles and Fields, 2020
Observation of the interference between the atmospheric and solar oscillation waves with the correct magnitude would provide another manifestation of the three-generation structure of leptons.
