Dymnikova Black Hole Tidal Forces
M. H. Macêdo, A. A. M. Silva, R. R. Landim
In this work we investigate the tidal properties of the Dymnikova regular black hole and their ef fects on massive particles in radial free-fall. Starting from Dymnikova static, sp…
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…
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_…
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…
