Heavy Neutral Leptons in Neutrino Telescopes

Atmospheric Heavy Neutral Leptons are being studied in neutrino telescopes to search for GeV Heavy Neutral Leptons, with a focus on their production in cosmic showers, flux at detectors, and signals from decay. Research explores minimal and non-minimal scenarios, revealing opportunities to probe a wide range of mean lifetime values at the Lifetime Frontier.

1. Searching for atmospheric Heavy Neutral Leptons in Neutrino Telescopes Based on 1910.12839 & 1911.09129 V ctor Mu oz IFIC, UV/CSIC XIX International Workshop on Neutrino Telescopes

2. Why search for GeV Heavy Neutral Leptons? Neutrino Masses HNL

3. Atmospheric Heavy Neutral Leptons

4. Atmospheric Heavy Neutral Leptons Production in cosmic showers HNL

5. Atmospheric Heavy Neutral Leptons Flux at detector

6. Atmospheric Heavy Neutral Leptons Signal from the decay of the HNL HNL

7. Heavy Neutral Leptons in minimal scenario Coloma, Hern ndez, Mu oz, Shoemaker, 1911.09129
