I will discuss scenarios in which dark matter emerges as a matter of some hidden gauge sector, with microphysics similar or exactly same as that of ordinary particles. I will show that B-L violating interactions between the particles of ordinary and hidden sectors can give rise to a baryogenesis/leptogenesis scenario that co-generates both ordinary and dark matters in proper proportions. Second, these interactions can lead to particle mixing phenomena between two sectors (neutrinos, neutrons, etc.) which can be tested at small scale experiments. Third, such interactions can be interesting in view of dark matter direct detection.
