ABSTRACT:
The LHC experiment has not revealed new physics beyond the Standard Model so far. On the other hand cosmological observations tell us that dark matter must exist. Properties of the dark matter particle are barely known. At the same time, the mechanism to generate the flavor structure of the Standard Model is unknown. It is possible that a similar mechanism might operate in the dark sector, providing dark matter with a flavor structure. In particular we study possibility of dark matter entering flavor physics via flavor interactions with a quark and a colored mediator. In contrast to previous studies we do not assume Minimal Flavor Violation. In this case flavor observables such as particle - antiparticle mixing and rare decays as well as the decay B to X_s gamma have to be carefully studied, since they are very sensitive to new sources of flavor violation. We show that some specific flavor structures beyond Minimal Flavor Violation are also safe from constraints. We highlight the dark matter phenomenology of the allowed model space.
