KATRIN, a Next Generation Tritium β Decay Experiment in Search for the Absolute Neutrino Mass Scale

摘要

With the compelling evidence for massive neutrinos from recent ν-oscillation experiments, one of the most fundamental tasks of particle physics over the next years will be the determination of the absolute mass scale f neutrinos, which has crucial implications for cosmology, astrophysics and particle physics. A next generation tritium β decay experiment, the Karlruhe Tritium Neutrino experiment (KATRIN), is proposed to reach a sub eV sensitivity on the absolute mass of the electron neutrino.
