Confronting the low-scale seesaw and leptogenesis with neutrinoless double beta decay
J. de Vries, M. Drewes, Y. Georis +2
We revisit the impact of heavy neutrinos with masses in the MeV-GeV range on neutrinoless double beta decay () in view of updated results for the lifetime of this process.…

Probing Solar Heavy Neutrinos with Heliospheric Electrons
Marco Drewes, Jan Heisig, Valentin Weber
We search for an excess of electrons and positrons in the interplanetary space from the decays of heavy neutrinos produced in nuclear reactions in the Sun. Using measurements of th…

Prospects for Heavy Neutral Lepton Searches at Short and Medium Baseline Reactor Experiments
N. van Remortel, M. Colomer Molla, B. Clerbaux +6
Heavy neutrinos with masses in the MeV range can in principle simultaneously explain the light neutrino masses and the origin of baryonic matter in the universe. The strongest cons…
