Grand Unified Neutrino Spectrum at Earth: Sources and Spectral Components
Edoardo Vitagliano, Irene Tamborra, Georg Raffelt
We briefly review the dominant neutrino fluxes at Earth from different sources and present the Grand Unified Neutrino Spectrum ranging from meV to PeV energies. For each energy ban…
Fast Neutrino Flavor Conversion: Collective Motion vs. Decoherence
Francesco Capozzi, Georg Raffelt, Tobias Stirner
In an interacting neutrino gas, flavor coherence becomes dynamical and can propagate as a collective mode. In particular, tachyonic instabilities can appear, leading to "fast flavo…
Distinguishing Dirac and Majorana neutrinos by their gravi-majoron decays
Lena Funcke, Georg Raffelt, Edoardo Vitagliano
Neutrinos may acquire small Dirac or Majorana masses by new low-energy physics in terms of the chiral gravitational anomaly, as proposed by Dvali and Funcke (2016). This model pred…
Future Opportunities in Accelerator-based Neutrino Physics
Andrea Dell'Acqua, Antoni Aduszkiewicz, Markus Ahlers +140
This document summarizes the conclusions of the Neutrino Town Meeting held at CERN in October 2018 to review the neutrino field at large with the aim of defining a strategy for acc…
A new experimental approach to probe QCD axion dark matter in the mass range above 40eV
The MADMAX Collaboration, P. Brun, A. Caldwell +28
The axion emerges in extensions of the Standard Model that explain the absence of CP violation in the strong interactions. Simultaneously, it can provide naturally the cold dark ma…
