MSc Project: A combined fit of neutrino models using astrophysics and oscillation experiments Prof. Stefan Söldner-Rembold Sterile Neutrinos • Most models that explain small neutrino masses (see-saw) predict ‘sterile’ neutrinos. • Sterile means they only interact gravitationally through their mass, but not through weak interaction. • Sterile neutrino masses can be anywhere between 1 eV and GUT scale. Short-baseline Anomalies (electron-neutrinos) Reactor anomaly Sterile neutrinos? LSND νe appearance 30 May 2016 MiniBooNE low energy excess S Söldner-Rembold - SBN Programme 3 Sterile neutrinos modify oscillations (“particle physics”) sterile neutrinos modify CMB (astrophysics/cosmology) Translating the Parameter Space Muon-Neutrino Disappearance Joint project with Astronomers • Will be supported by Prof. Sarah Bridle (Astro) • Include electron-neutrino data, including anomalies, for accelerator/reactor experiments. • Use same statistical methods for both data set (currently not done) • Expand to more than just 3+1 flavour, study impact of various mixing angles • publish.
