Description
The KATRIN experiment aims at direct kinematic measurement of the neutrino mass with the expected sensitivity below 300 meV (90% CL), performing a high-resolution, high-statistics spectroscopy of tritium beta-decay. To reach such sensitivity, the systematic effects, modifying the measured electron spectrum shape have to be modeled and controlled by dedicated calibration measurements.
KATRIN obtained the world-leading direct constraint on the effective mass of the electron antineutrino of 0.45 eV (90% CL) using only 16% of the data. The final dataset of KATRIN contains 1000 days of tritium spectra recorded by the end of 2025 and therefore increases the statistics by a factor of 6 compared to previous results.
In this talk after introducing the framework of the analysis, the challenges and steps towards the analysis of the full KATRIN dataset are presented.
