Improved eV-scale Sterile-Neutrino Constraints from the Second KATRIN Measurement Campaign

M. Aker, D. Batzler, A. Beglarian +128

We present the results of the light sterile neutrino search from the second KATRIN measurement campaign in 2019. Approaching nominal activity, $3.76\times 10^6$ tritium $\beta$-electr…
