We study a simplified Dark Matter model in the Dark Minimal Flavour Violationframework. Our model complements the Standard Model with a flavoured DarkMatter Majorana triplet and a coloured scalar mediator that share a Yukawacoupling with the right-handed up-type quarks with the coupling matrix$\lambda$. We extend previous work on this topic by exploring a large range ofcosmologically viable parameter space, including the coannihilation region and,in particular, the region of conversion-driven freeze-out, while consideringconstraints from $D^0-\bar D^0$ mixing as well as constraints from direct andindirect Dark Matter searches. We find various realisations ofconversion-driven freeze-out within the model, that open up allowed windows ofparameter space towards small mass splittings and very weak Dark Mattercouplings. Finally, we probe the model by reinterpreting current LHC searchesfor missing energy and long-lived particles. We point out gaps in the coverageof current constraints as well as new opportunities to search for the model atthe LHC, in particular, the charge asymmetry in single-top productionassociated with jets and missing energy.
