abstract
It has been proposed that two resonances could coincide in the early universe at temperatures $T \sim 0.2 ... 0.5$ GeV: one between two nearly degenerate GeV-scale sterile neutrinos, producing a large lepton asymmetry through freeze-out and decays; another between medium-modified active neutrinos and keV-scale sterile neutrinos, converting the lepton asymmetry into dark matter. Making use of a framework which tracks three sterile neutrinos of both helicities as well as three separate lepton asymmetries, and scanning the parameter space of the GeV-scale species, we establish the degree of fine-tuning that is needed for realizing this scenario.

Probing Solar Heavy Neutrinos with Heliospheric Electrons
Using Ulysses and SOHO MeV electron data, the authors set the strongest direct upper bound U_e^2 ~ 10^-6 on solar-produced heavy neutral leptons, reaching that value at a mass near 10 MeV.

Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis
For four flavour-symmetry cases, this paper maps heavy-neutrino lifetimes, decay flavour ratios, and the parameter space where leptogenesis works and colliders can test it.

Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt signatures in the ATLAS detector
The ATLAS search finds no evidence of heavy neutral leptons in W boson decays and sets the strongest limits to date on their mixing with electron and muon neutrinos in the 15-30 GeV mass range.
