Neutrino flavor mixing breaks isotropy in the early universe
Rasmus S. L. Hansen, Shashank Shalgar, Irene Tamborra
The neutrino field is commonly assumed to be isotropic and homogeneous in the early universe. However, due to the large neutrino density, a small perturbation of the isotropy of th…
Pseudoscalar - sterile neutrino interactions: reconciling the cosmos with neutrino oscillations
Maria Archidiacono, Stefano Gariazzo, Carlo Giunti +4
The Short BaseLine (SBL) neutrino oscillation anomalies hint at the presence of a sterile neutrino with a mass of around 1 eV. However, such a neutrino is incompatible with cosmolo…
Sterile neutrinos with pseudoscalar self-interactions and cosmology
Maria Archidiacono, Steen Hannestad, Rasmus Sloth Hansen +1
Sterile neutrinos in the electronvolt mass range are hinted at by a number of terrestrial neutrino experiments. However, such neutrinos are highly incompatible with data from the C…
Cosmology with self-interacting sterile neutrinos and dark matter - A pseudoscalar model
Maria Archidiacono, Steen Hannestad, Rasmus Sloth Hansen +1
Short baseline neutrino oscillation experiments have shown hints of the existence of additional sterile neutrinos in the eV mass range. Such sterile neutrinos are incompatible with…
How secret interactions can reconcile sterile neutrinos with cosmology
Steen Hannestad, Rasmus Sloth Hansen, Thomas Tram
Short baseline neutrino oscillation experiments have shown hints of the existence of additional sterile neutrinos in the eV mass range. However, such neutrinos seem incompatible wi…
Can active-sterile neutrino oscillations lead to chaotic behavior of the cosmological lepton asymmetry?
Steen Hannestad, Rasmus Sloth Hansen, Thomas Tram
While the cosmic baryon asymmetry has been measured at high accuracy to be 6.1*10^-10, a corresponding lepton asymmetry could be as large as 10^-2 if it hides in the neutrino secto…
