In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also by experimental searches and cosmological considerations. In the existing literature, three disjoint regions of potentially viable parameter space have been identified. In one of them, all heavy neutrinos decay shortly before big bang nucleosynthesis. In the other two regions, one of the heavy neutrinos either decays between BBN and the CMB decoupling or is quasi-stable. We show that previously unaccounted constraints from photodisintegration of nuclei practically rule out all relevant decays that happen between BBN and the CMB decoupling. Quite remarkably, if all heavy neutrinos decay before BBN, the baryon asymmetry of the universe can be quite generically explained by low-scale leptogenesis, i.e. without further tuning in addition to what is needed to avoid experimental and cosmological constraints. This motivates searches for heavy neutrinos in pion decay experiments. 000455482 536__ $$0G:(DE-HGF)POF4-611$$a611 - Fundamental Particles and Forces (POF4-611)$$cPOF4-611$$fPOF IV$$x0 000455482 536__ $$0G:(GEPRIS)390833306$$aEXC 2121 - Das Quantisierte Universum (390833306)$$c390833306$$fDFG EXC 2121$$x1 000455482 536__ $$0G:(EU-Grant)638528$$aNewAve - New avenues towards solving the dark matter puzzle (638528)$$c638528$$fERC-2014-STG$$x2 000455482 588__ $$aDataset connected to CrossRef, INSPIRE 000455482 650_7 $$2INSPIRE$$a* Automatic Keywords * 000455482 650_7 $$2INSPIRE$$anucleosynthesis: big bang 000455482 650_7 $$2INSPIRE$$aneutrino: heavy: decay 000455482 650_7 $$2INSPIRE$$acosmic background radiation: decoupling 000455482 650_7 $$2INSPIRE$$aneutrino: heavy 000455482 650_7 $$2INSPIRE$$aneutrino: decay 000455482 650_7 $$2INSPIRE$$aneutrino: mass 000455482 650_7 $$2INSPIRE$$aneutrino: heavy: search for 000455482 650_7 $$2INSPIRE$$aneutrino: right-handed 000455482 650_7 $$2INSPIRE$$api: decay 000455482 650_7 $$2INSPIRE$$api: mass 000455482 650_7 $$2INSPIRE$$amass: Majorana 000455482 650_7 $$2INSPIRE$$abaryon: asymmetry 000455482 650_7 $$2INSPIRE$$aleptogenesis 000455482 650_7 $$2INSPIRE$$aseesaw model 000455482 650_7 $$2INSPIRE$$anucleus 000455482 650_7 $$2autogen$$aBeyond Standard Model 000455482 650_7 $$2autogen$$aCosmology of Theories beyond the SM 000455482 650_7 $$2autogen$$aNeutrino Physics 000455482 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000455482 7001_ $$aDrewes, Marco$$b1 000455482 7001_ $$0P:(DE-H253)PIP1032760$$aHufnagel, Marco$$b2 000455482 7001_ $$0M.Lucente.1$$aLucente, Michele$$b3 000455482 773__ $$0PERI:(DE-600)2027350-2$$a10.1007/JHEP01(2021)200$$gVol. 01, no. 1, p. 200$$n1$$p200$$tJournal of high energy physics$$v01$$x1029-8479$$y2021 000455482 7870_ $$0PUBDB-2020-03620$$aDomcke, Valerie Fiona et.al.$$d2020$$iIsParent$$rarXiv:2009.11678 ;
