From Unified Theories to Precision Neutrino Experiments
Stefan Antusch

The expected high sensitivities of future neutrino experiments will allow precision tests of unified models. In order to compare GUT scale predictions with experimental results obtained at low energy, the renormalization group running of the neutrino mass parameters has to be taken into account. The running is particularly relevant, if the neutrino mass spectrum turns out to be non-hierarchical or if the lepton mixing angles turn out to be close to specific values such as $0$ for $\theta_{13}$, $\pi/4$ for $\theta_{23}$ or $\pi/4 - \theta_C$, with $\theta_C$ being the Cabibbo angle, for $\theta_{12}$.
