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.

Strengths
1. This manuscript provides a case study of benchmark dark matter models using EFT in the GAMBIT framework.
2. The writing is concise and clear, in both illustrating that GAMBIT is powerful in constraining weak-scale dark matter candidates, and the discussion of the EFT validity in the framework.
Report
I recommend the publication of this manuscript in SciPost Physics Proceedings, as it transcends the criteria.

Report
In this proceeding highlights and key achievements of a first global analysis of full set of effective operators for a Dirac fermion dark-matter interaction with Standard-Model quarks are presented. It is made use of a new approach to address the issue of the validity of an effective-field-theory treatment at the LHC, which relies on efficient likelihood calculations and sampling algorithms to sample a 14-dimensional model parameter space.
A public link on results, samples and input files is also provided.
The manuscript is clearly written and well organized.
It is also suitably formatted for publication.
I recommend the manuscript for publication in its present form.
