Description
We consider a simple renormalizable model providing a UV completion
for dark matter whose interactions with the Standard Model are primarily
via the gluons. The model consists of scalar dark matter interacting
with scalar colored mediator particles. A novel feature is the fact
that (in contrast to more typical models containing scalar dark matter interacting with gluons)
the colored scalars typically decay into multi-quark final states,
with no associated missing energy. We construct this class of models
and examine associated phenomena related to dark matter annihilation,
scattering with nuclei, and production at colliders. We compare the
results obtained from effective field theory (EFT) with a loop-induced
calculations for the collider processes and show that EFT is not applicable
for a large parameter space where mediator mass is comparable to the
cuts on missing energy. We calculate the bounds from from $\sqrt{s}=$ 8 and 13 TeV data and show the expected reach of $\sqrt{s}=$ 14 TeV LHC and 100 TeV FCC in constraining or discovering the model.
