12. Massive spin-2 mediated dark matter

A massive spin-2 particle can act as the mediator between dark matter and standard model particles through the energy momentum tensor in the spin-2 mediated dark matter model. The scattering amplitudes between dark matter and standard model particles are examined by effective theory and consisted of effective operators after the mediator is integrated out. The differential event rate with...

13. Time-information at colliders

We study the kinematics of long-lived particles which decay inside the detector using precision timing information. We consider the event with two long-lived particles which decay to visible and invisible particles. We reconstruct 4-momentum of long-lived particles as well as invisible particles by solving kinematic equations with and without the timing information. Without using the timing...

14. Phenomenology of dark gauge group at the LHC

A dark sector which contains dark matter may have its own gauge group structure. Depending on a gauge structure and corresponding charge of dark matter, collider phenomenology can be different. In this talk, I will talk about U(1) and SU(3) dark gauge group and distinctive signature at the LHC.

15. Energetic axion-like particles from decaying dark matter

Kyu Jung Bae (IBS)

We consider a model of decaying axino-like particle dark matter with lifetime around the age of the universe. Its late decay to gravitino plus axion-like particle is able to solve small-scale problems. We will also show a distinct signature of the axion-like particle from the axino-like particle decay.
