Titre |
Primordial high energy neutrinos |
|
Résumé |
In this talk, I will discuss the prospects for detecting high energy neutrinos
produced before recombination by the decay or annihilation of early Universe
relics. The focus is on identifying sharp spectral features, influenced by
cosmological redshift and radiative effects, and determining when these features
remain intact or are erased by interactions on the way to the detector. I will
outline the viable ranges of particle mass, lifetime, and abundance consistent
with cosmological and observational constraints, and identify which regions of
parameter space remain promising for future searches. I will also briefly present
our Monte Carlo treatment of spectral distortions of the primordial high energy
neutrino spectrum induced by scattering on the cosmic neutrino background. |
