When inverse seesaw meets inverse electroweak phase transition: a novel path to leptogenesis
Wen-Yuan Ai, Peisi Huang, Ke-Pan Xie
We propose a new nonthermal leptogenesis mechanism triggered by the cosmic first-order phase transition. The Standard Model is extended with two generations of TeV-scale vectorlike…
Testable Flavored TeV-scale Resonant Leptogenesis with MeV-GeV Dark Matter in a Neutrinophilic 2HDM
Peisi Huang, Kairui Zhang
We explore flavored resonant leptogenesis embedded in a neutrinophilic 2HDM. Successful leptogenesis is achieved by the very mildly degenerate two heavier right-handed neutrinos (R…
Leptogenesis with dynamical couplings
Peisi Huang, Tao Xu
We propose a novel leptogenesis mechanism with a temperature-dependent coupling between the right-handed neutrino and Standard Model particles. This coupling experiences suppressio…
Enhanced Dark Matter Abundance in First-Order Phase Transitions
Rouzbeh Allahverdi, Cash Hauptmann, Peisi Huang
We propose a novel scenario to obtain the correct relic abundance for thermally under-produced dark matter. This scenario utilizes a strongly first-order phase transition at temper…
