Abstract

We present the phenomenology of a simplified dark matter model within the dark minimal flavor violation framework, extending the standard model with a Majorana fermion flavor triplet and colored scalar mediator. We explore the allowed parameter space considering constraints from flavor observables, direct and indirect dark matter detection, and the relic density measurement. Our analysis reveals previously unexplored scenarios such as conversion-driven freeze-out within the model. We study limits from the LHC and discuss new signatures of the model, highlighting its richer phenomenology compared to single flavor dark matter.
