KATRIN and sterile Neutrinos in the eV mass range — •Marc Korzeczek¹, Thierry Lasserre², and Susanne Mertens^1,3 for the KATRIN collaboration — ¹Karlsruhe Institute of Technology, Germany — ²Commissariat à l'énergie atomique, France — ³Lawrence Berkeley National Laboratory, USA

Sterile neutrinos in the eV-mass range could resolve a number of longstanding anomalies in short baseline neutrino oscillation experiments. The KATRIN Experiment (KArlsruhe TRItium Neutrino) designed to measure the mass of the active neutrino, has the potential to search for a signature of light sterile neutrinos without any hardware modification.

In this talk we explore the combined sensitivity of KATRIN with CeSOX (CErium Short distance neutrino Oscillations with boreXino), an experiment dedicated to search for light sterile neutrinos via oscillations. In particular, we study the impact of sterile neutrinos on the KATRIN's active neutrino mass measurement.
