Spontaneous Leptogenesis in Type I Seesaw
Eung Jin Chun, Hyun Min Lee, Jun-Ho Song
Type-I seesaw models with a spontaneously broken symmetry provide a natural framework for spontaneous leptogenesis driven by a Majoron. The kinetic background of the Majoron…

Self-resonant dark matter with gauged symmetry
Lucca Radicce Justino, Seong-Sik Kim, Hyun Min Lee +1
We present a new model for two-component scalar dark matter (DM), consisting of two complex scalar fields. In this model, both the DM components are stable due to the remaining $Z_…

Higgs pole inflation with loop corrections in light of ACT results
Jeonghak Han, Hyun Min Lee, Jun-Ho Song
We present the Coleman-Weinberg potential for the inflaton in the pole inflation scenarios such as the Higgs pole inflation and the Peccei-Quinn (PQ) pole inflation. The loop corre…
