Neutrino physics from heaven and earth

Thomas Schwetz-Mangold

KIT

In this talk I give an overview of the current status of neutrino mass and mixing parameters, by first discussing the determination of the three flavour oscillation parameters from a global analysis, discussing the status of leptonic CP violation and the type of the neutrino mass ordering. Then I discuss absolute neutrino mass determinations, high-lighting the interplay of cosmological and terrestrial methods. Indeed, cosmology has excellent sensitivity and in the standard scenario we expect to see a finite neutrino mass in CMB and large-scale structure observables in the near future. I comment on the possibility to determine the neutrino mass ordering using cosmology. In the last part of the talk I will comment on the robustness of cosmological observations and present a specific seesaw model for neutrino mass as an example of how to make “large” neutrino masses consistent with cosmology.
