Abstract: In this proceeding, we present results from a global fit of Dirac fermion dark matter (DM) effective field theory (EFT) based on arXiv:2106.02056 using the GAMBIT framework.Here we show results only for the dimension-6 operators that describe the interactions between a gauge-singlet Dirac fermion and Standard Model quarks.Our global fit combines the latest constraints from Planck, direct and indirect DM detection, and the LHC.For DM mass below 100 GeV, it is impossible to simultaneously satisfy all constraints while maintaining the EFT validity at high energies.For higher masses, however, large regions of parameter space remain viable where the EFT is valid and saturates the observed DM abundance.
