I will present the phenomenology of flavored dark matter (DM). DM stability is guaranteed by an accidental Z3 symmetry, a subgroup of the standard model (SM) flavor group that is not broken by the SM Yukawa interactions. I will consider an explicit realization where the quark part of the SM flavor group is fully gauged. If the dominant interactions between DM and visible sector are through flavor gauge bosons as for Dirac fermion DM, then in the minimal model the DM mass is bounded between roughly 0.5TeV and 5TeV by LHC di-jet resonance searches and perturbativity arguments, respectively. In general, however, no such relations exists. I will demonstrate this using scalar flavored DM, where the main interaction with the SM is through the Higgs portal. For both cases I will discuss constraints from flavor, cosmology, direct and indirect DM detection, and collider searches.
