The KM3NeT event: a primordial high energy neutrino?
Nicolas Grimbaum Yamamoto, Thomas Hambye
High energy neutrinos can be injected in the early Universe from the decay or annihilation of long lived primordial relics. We analyse the possibility that the ultrahigh energy neu…
Keeping It Renormalizable: Minimal Baryogenesis induced Asymmetric Dark Matter
Miguel Escudero, Thomas Hambye, Chandan Hati
Many asymmetric dark matter scenarios have been proposed to date. Among them, perhaps the most motivated ones are those in which the dark matter asymmetry is induced from the baryo…
Primordial high energy neutrinos: theoretical/observational constraints and sharp spectral features
Nicolas Grimbaum Yamamoto, Thomas Hambye
Among the few ways that allow or could allow us to probe the early Universe from the observation of a flux of primordial particles, there is one possibility which has been little s…
The Simplest Dark Matter Model at the Edge of Perturbativity
Miguel Escudero, Thomas Hambye
Increasingly sensitive direct detection dark matter experiments are testing important regions of parameter space for WIMP dark matter and pushing many models to the multi-TeV regim…
Photo- and Hadrodisintegration constraints on massive relics decaying into neutrinos
Sara Bianco, Paul Frederik Depta, Jonas Frerick +3
We perform a detailed study of the cosmological constraints on the decay of a relic particle into neutrinos, , in particular those arising from the obs…
