Abstract

The minimal vector dark matter is a viable realization of the minimal dark matter paradigm. It extends the standard model by the inclusion of a vector matter field in the adjoint representation of (Formula presented.). The dark matter candidate corresponds to the neutral component of the new vector field ((Formula presented.)). Previous studies have shown that the model can explain the observed dark matter abundance while evading direct and indirect searches. At colliders, the attention has been put on the production of the charged companions of the dark matter candidate. In this work, we focus on the mono-Higgs and mono-Z signals at Hadron colliders. The new charged vectors ((Formula presented.)) are invisible unless a dedicated search is performed. Consequently, we assume that the mono-Higgs and mono-Z processes correspond to the (Formula presented.) and (Formula presented.) reactions, respectively. We show that, while the (Formula presented.) is more important, both channels may produce significant signals at the HL-LHC and colliders running at (Formula presented.) TeV and 100 TeV, probing almost the complete parameter space. © 2024 by the authors.
