Inelastic dark matter and baryon flavor symmetry in light of LUX-ZEPLIN (LZ) experiment
Hyun Min Lee
We present a novel model for inelastic dark matter in a simple extension of the Standard Model (SM) with a local baryon flavor symmetry, such as with $i\ne…

Gravity-Mediated Dark Matter at a low reheating temperature
Hyun Min Lee, Myeonghun Park, Veronica Sanz
We present a new study on the Gravity-Mediated Dark Matter (GMDM) scenario, where interactions between dark matter (DM) and the Standard Model are mediated by spin-two particles. E…

Nonthermal Heavy Dark Matter from a First-Order Phase Transition
Gian F. Giudice, Hyun Min Lee, Alex Pomarol +1
We study nonthermal production of heavy dark matter from the dynamics of the background scalar field during a first-order phase transition, predominantly from bubble collisions. In…
