SUMMARY:A New Dark Matter (in)Direct Search Strategy\, Theory Seminar 
 (High Energy/Cosmology)\, Doo Jin Kim\, CERN
DESCRIPTION:I propose a new dark matter (DM) detection strategy for mo
 dels with a non-minimal dark sector. The strategy is to seach for rela
 tivistic\, inelastic scattering signatures of DM at large-volume neutr
 ino detectors and/or conventional DM direct detection experiments via 
 a DM interaction with target material inside the detector. The signal 
 process is characterized by an inelastic scattering of relativistic/bo
 osted DM\, which may arise in multi-component DM scenarios\, into a he
 avier unstable dark-sector state which subsequently decays back into D
 M along with visible particles. I will argue that the presence of the 
 secondary (visible) decay signature along with an energetic target rec
 oil is very unique\, hence allow to unambiguously separate signal even
 ts from associated background ones. I will then dicuss some interestin
 g phenomenology including detection prospects at the above-mentioned e
 xperiments\, taking the dark photon scenario as a benchmark model.
