Neutrino directionality: aims, methods and the reaction of inverse beta decay — •Yaroslav Nikitenko, Philipp Soldin, Achim Stahl, and Christopher Wiebusch — III. Physikalisches Institut B, RWTH Aachen University

Reconstructing the direction of neutrinos is of high interest for supernovae and geoneutrinos. We discuss existing experimental methods and focus on neutrino directionality using the reaction of inverse beta decay.

While the reaction of neutrino-electron scattering provides a better per-event angular resolution for supernova neutrinos, inverse beta decay usually has many more events. Its detection threshold for existing large detectors is lower than that for electron scattering, which is important for geoneutrinos.

The Double Chooz reactor neutrino experiment provides a good scientific basis to study neutrino directionality with the reaction of inverse beta decay. Its advantage is the neutrino source of a known direction and almost point-like structure.
