Impact of ATLAS constraints on effective dark matter-standard model interactions with spin-one mediators

Abstract

We complement a previous work \cite{Fortuna:2020wwx} using an EFT framework of dark matter and standard model interactions, with spin-one mediators, exploring a wider dark matter mass range, up to $6.4$ TeV. We use again bounds from different experiments: relic density, direct detection experiments and indirect detection limits from the search of gamma-ray emissions and positron fluxes. Besides, in this paper we add collider constraints by the ATLAS Collaboration in monojet analysis. Moreover, here we tested our previous results in the light of the aforementioned ATLAS data, which turn out to be the most restrictive forlight dark matter masses (as expected), $m_{\rm DM}<M_Z/2$. We obtain a larger range of solutions for the operators of dimension 5, OP1 and OP4, where masses above $43$ GeV and $30$ GeV (but for the $Z$ resonance region, $\sim (M_Z\pm\Gamma_Z)/2$), respectively, are allowed. In contrast, the operator of dimension 6, OP3, has viable solutions for masses $\gtrsim 190$ GeV. For the combination of OP1\&OP3 we obtain solutions (for masses larger than $140$ or $325$ GeV) that depend on the relative sign between the operators.
