KATRIN bound on 3+1 active-sterile neutrino mixing and the reactor antineutrino anomaly

C. Giunti, Y. F. Li, Y. Y. Zhang

We present the bounds on 3+1 active-sterile neutrino mixing obtained from the first results of the KATRIN experiment. We show that the KATRIN data extend the Mainz and Troitsk boun…
