                            Description
                                    A search is presented for an excess of events with heavy-flavor quark
pairs ({t}\overline{{t}} and {b} \overline{{b}} ) and a large imbalance
in transverse momentum in data from proton-proton collisions at a
center-of-mass energy of 13 TeV. The data correspond to an integrated
luminosity of 2.2 fb^{-1} collected with the CMS detector at the CERN
LHC. No deviations are observed with respect to standard model
predictions. The results are used in the first interpretation of dark
matter production in {t}\overline{{t}} and {b} \overline{{b}} final
states in a simplified model. This analysis is also the first to perform
a statistical combination of searches for dark matter produced with
different heavy-flavor final states. The combination provides exclusions
that are stronger than those achieved with individual heavy-flavor final
states.
