Neutrino Physics


    Neutrino oscillations indicate that neutrinos have non-vanishing mass, which points towards physics beyond the Standard Model of elementary particle physics. Three types of neutrinos are known, and the ordering of their masses gives important clues about the underlying theory. It may be determined by new technologies currently under development, such as PINGU (Precision IceCube Next Generation Upgrade).

    Furthermore, CP violation may indicate that neutrinos are involved in generating the observed matter-antimatter asymmetry in the early universe. The precision measurement of CP violation requires a new dedicated long-baseline neutrino oscillation experiment.

    We study the potential of future neutrino oscillation experiments regarding such measurements, new physics effects, and even the structure of the Earth -- which the experiments are sensitive to. We furthermore investigate models for neutrino masses and mixings, and their implications in, e.g., collider phenomenology. Since new physics may be relevant in extreme environments, at extreme distances, or at extreme energies, we constrain neutrino properties in astrophysical environments or over cosmological distances as well.
