Baryogenesis and first-order QCD transition with gravitational waves from a large lepton asymmetry

Fei Gao, Julia Harz, Chandan Hati, Yi Lu et al. • Journal of High Energy Physics (2025)

Abstract A large primordial lepton asymmetry can lead to successful baryogenesis by preventing the restoration of electroweak symmetry at high temperatures, thereby suppressing the sphaleron rate. This asymmetry can also lead to a first-ord...
