Physikalisches Kolloquium: Dr. Phillipp Eller – Towards a Unified Picture of Atmospheric Neutrino Oscillations

Titel: Towards a Unified Picture of Atmospheric Neutrino Oscillations

Abstract:
Atmospheric neutrinos provide a unique probe of neutrino oscillations over a wide range of energies and baselines, traversing the Earth through regions of varying matter density. Over the past decades, experiments such as Super‑Kamiokande and IceCube--and more recently KM3NeT/ORCA--have collected large atmospheric neutrino data sets, each offering complementary strengths in energy coverage, angular resolution, and control of systematic uncertainties.

In this talk, I will present a combined analysis of atmospheric neutrino data from these experiments, aiming to exploit their complementarity within a common oscillation framework. By bringing together measurements from water‑ and ice‑Cherenkov detectors with different energy thresholds and detector configurations, this approach provides a more global and robust view of atmospheric neutrino oscillations, reducing sensitivity to detector‑specific effects.

Beyond the physics results, this analysis also follows a new avenue by being fully open‑source from the outset, enabling transparent, community‑driven development and establishing a flexible foundation for future neutrino oscillation studies and global fits.
