Light sterile neutrino search with KATRIN — •Fotios Megas for the KATRIN collaboration — Technische Universität München, München, Deutschland — Max-Planck-Institut für Physik, München, Deutschland
The KATRIN experiment aims to measure the effective electron antineutrino mass, with an unprecedented sensitivity of 0.2 eV/c2. Being sensitive in this mass range means that KATRIN can also be used to resolve another puzzling phenomenon:
Anomalies observed in short baseline and reactor experiments may be resolved by the existence of light sterile neutrinos. KATRIN has the potential to shed light onto these anomalies.
This talk will present the sensitivity of KATRIN to light sterile neutrinos. Focus will be put on the effect of background, systematic uncertainties and different measurement schemes. Finally, the analysis method will be applied to the first tritium data acquired in summer 2018, as a test study.
