(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
The problems of neutrino masses, matter-antimatter asymmetry, and dark matter could be successfully addressed by postulating right-handed neutrinos with Majorana masses below the electroweak scale. In this work, leptonic ...
