Abstract: Recently, Belle II has reported excess in B -> K nu barn. Since the neutrinos in the final states are not identified, the excess may be due to some "invisible" states. Proposal has been made to take the "invisible" to be a light dark matter pair to explain the excess. To have a consistent explanation, one should also look into dark matter relic density and direct detection of dark matter.
We find that these considerations constraint theoretical model buildings severely. In this talk I will report our effort to build a consistent theoretical renormalizable model.
