Leptogenesis from composite singlets
Year: 2024
Type: article
Abstract: We argue that dual singlets accommodate the thermal leptogenesis in the context of metastable supersymmetry breaking. This framework suggests that the reheating temperature is as low as O(104) GeV , and besides the neutrino masses, solely induced from the dual fermions, are present at O(0.1) eV . We also expect that the unstable gravitino, though long-lived, may cause a clear signal of the neutrino flux at O(10) MeV . Published by the American Physical Society 2024
