Dark and visible matter with broken R-parity and the axion multiplet by Hasenkamp, Jasper, Kersten, Jörn

“…A small breaking of R-parity reconciles thermal leptogenesis, gravitino dark matter and primordial nucleosynthesis. We find that the same breaking relaxes…”

Daughters mimic sterile neutrinos (almost!) perfectly by Hasenkamp, Jasper

“…Since only recently, cosmological observations are sensitive to hot dark matter (HDM) admixtures with sub-eV mass, $m_\text{hdm}^\text{eff}$ < eV, that are not…”
