* Title: Isocurvature constraints on portal couplings


* Speaker: Kunio Kaneta (CTPU Seminar room - KAIST Munji Campus)

 

* Date: 3:00~4:00 PM, 4 Feb 2015

 

* Abstract: When interactions among the SM sector and dark matter are feeble, the freeze-in mechanism becomes efficient for the dark matter production. In this case, the dark matter never enter the thermal bath unlike the conventional freeze-out scenario, and is produced by non-thermal way. I will briefly review the freeze-in dark matter production, and show the constraints from isocurvature perturbations.
