Baryogenesis and first-order QCD transition with gravitational waves from a large lepton asymmetry
Fei Gao, Julia Harz, Chandan Hati +3
A large primordial lepton asymmetry can lead to successful baryogenesis by preventing the restoration of electroweak symmetry at high temperatures, thereby suppressing the sphalero…

LiteBIRD and CMB-S4 Sensitivities to Reheating in Plateau Models of Inflation
Marco Drewes, Lei Ming, Isabel Oldengott
We study the sensitivity of LiteBIRD and CMB-S4 to the reheating temperature and the inflaton coupling in three types of plateau-potential models of inflation, namely mutated hillt…

Local clustering of relic neutrinos: Comparison of kinetic field theory and the Vlasov equation
Emil Brinch Holm, Stefan Zentarra, Isabel M. Oldengott
Gravitational clustering in our cosmic vicinity is expected to lead to an enhancement of the local density of relic neutrinos. We derive expressions for the neutrino density, using…
