An improved upper limit on the neutrino mass from a direct kinematic method by KATRIN
M. Aker, K. Altenmüller, M. Arenz +205
We report on the neutrino mass measurement result from the first four-week science run of the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from…

High-resolution spectroscopy of gaseous Kr conversion electrons with the KATRIN experiment
K. Altenmüller, M. Arenz, W. -J. Baek +124
In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous Kr with the Karlsruhe Tritium…

Improved limits on nuebar emission from mu+ decay
B. Armbruster, I. M. Blair, B. A. Bodmann +21
We investigated mu+ decays at rest produced at the ISIS beam stop target. Lepton flavor (LF) conservation has been tested by searching for \nueb via the detection reaction p(\nueb,…
