Title:Dark matter, dark radiation and Higgs phenomenology in the hidden sector DM models

Authors:P. Ko (KIAS)

Abstract:I present a class of hidden sector dark matter (DM) models with local dark gauge symmetries, where DM is stable due to unbroken local dark gauge symmetry, or due topology, or it is long-lived because of some accidental symme- tries, and the particle contents and their dynamics are completely fixed by local gauge symmetries. In these models, one have two types of natural force mediators, dark gauge bosons and dark Higgs boson, which would affect DM and Higgs phenomenology in important ways. I discuss various phenomenological issues including the GeV scale gamma-ray excess from the galactic center (GC), (in)direct detection signatures, dark radiation, Higgs phenomenology and Higgs inflation assisted by dark Higgs.
