From Unified Theories to Precision Neutrino Experiments
  The expected high sensitivities of future neutrino oscillation experiments will allow precision tests of unified theories of flavour. In order to compare GUT scale predictions for neutrino masses, leptonic mixing angles and CP violating phases with experimental results obtained at low energy, their renormalization group running has to be taken into account. We discuss the running in seesaw scenarios, present analytical approximations as well as numerical tools, and compare the size of the running effects with the expected experimental sensitivities.
