Quantum sensors for a next-generation tritium-base neutrino mass experiment
Sebastian Kempf (KIT)
Auditorium (Bldg 5, DESY Hamburg) and Zoom, 16:00h
Determining the absolute neutrino mass scale is one of the remaining grand challenges in fundamental physics. Precision measurements of weak-decay kinematics provide the only model-independent route. The Karlsruhe Tritium Neutrino (KATRIN) experiment currently spearheads this effort and has recently set the world's tightest neutrino mass limit, by measuring the tritium β-decay spectrum.
Yet, probing the inverted or normal mass ordering lies far beyond KATRIN's reach and requires breakthroughs in both tritium source technology and electron spectroscopy. In this talk, I will discuss how superconducting quantum sensors, combined with an atomic tritium source, provide a suitable path towards a next-generation tritium-based neutrino mass measurement, aiming to probe or even resolve the neutrino mass ordering.
We invite you to attend the presentations in person at the DESY Auditorium in building 5. We will also offer a webcast for this colloquium.
