Spontaneous Scoto-leptogenesis
Arghyajit Datta, Hyun Min Lee, Jun-Ho Song
We propose a low-scale spontaneous leptogenesis scenario within the dynamical minimal scotogenic model for accommodating neutrino masses and inert scalar dark matter simultaneously…
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…
Inflation models with Peccei-Quinn symmetry and axion kinetic misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a consistent framework with the Peccei-Quinn (PQ) symmetry for obtaining the initial condition for axion kinetic misalignment from inflation. We introduce a PQ co…
Peccei-Quinn Inflation at the Pole and Axion Kinetic Misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a minimal extension of the Standard Model with the Peccei-Quinn (PQ) scalar field and explain the relic density of the QCD axion through the kinetic misalignment with a…
