DESCRIPTION:Speakers: Shaoping Li (Austrian Academy of Sciences)\n\nThe lo
 w-scale type-I seesaw is a well-motivated framework in which sterile neutr
 inos generate the Standard-Model neutrino masses\, can account for the mat
 ter-antimatter asymmetry and dark matter\, and may be probed at colliders.
  Two mechanisms have long dominated low-scale leptogenesis: resonant lepto
 genesis (RL)\, where the asymmetry is enhanced by near-degenerate sterile-
 neutrino masses\, and leptogenesis via sterile-neutrino oscillations (ARS)
 . In this talk\, I present a third mechanism\, thermally induced resonant 
 leptogenesis (TIRL)\, in which finite-temperature effects of the SM lepton
 s become important. I will explain how TIRL works and how it differs from 
 RL and ARS\, including the mass degeneracy of sterile neutrinos and resona
 nce from thermally resummed leptons.\n\nhttps://agenda.irmp.ucl.ac.be/even
