KATRIN Sensitivity to keV Sterile Neutrinos with the TRISTAN Detector Upgrade

H. Acharya, M. Aker, D. Batzler +127

Sterile neutrinos in the keV mass range are a well-motivated extension of the Standard Model and viable dark matter candidates. Their existence can be probed in laboratory experime…

Investigations of Charge Collection and Signal Timing in a multi-pixel Silicon Drift Detector

Christian Forstner, Korbinian Urban, Marco Carminati +7

Sterile neutrinos are a minimal extension of the Standard Model of particle physics and a promising candidate for dark matter if their mass is in the keV-range. The Karlsruhe Triti…

Investigation of Electron Backscattering on Silicon Drift Detectors for the Sterile Neutrino Search with TRISTAN

Daniela Spreng, Korbinian Urban, Marco Carminati +7

Sterile neutrinos are hypothetical particles in the minimal extension of the Standard Model of Particle Physics. They could be viable dark matter candidates if they have a mass in…
