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

Abstract

We complement a previous work [Fabiola Fortuna et al., Effective field theory analysis of dark matter-standard model interactions with spin one mediators, J. High Energy Phys. 02 (2021) 223.] using an effective field theory 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 again use bounds from different experiments: relic density, direct detection experiments, and indirect detection limits from the search of gamma-ray emissions and positron fluxes. Additionally, in this paper we add collider constraints by the ATLAS Collaboration in the monojet analysis. Moreover, here we tested our previous results in the light of the aforementioned ATLAS data, which turns out to be the most restrictive for light dark matter masses (as expected), ${m}_{\mathrm{DM}}<{M}_{Z}/2$. We obtain a larger range of solutions for the operators of dimension 5, OP1 and OP4, where masses above 43 GeV and 30 GeV [except for the $Z$-resonance region, $\ensuremath{\sim}({M}_{Z}\ifmmode\pm\else\textpm\fi{}{\mathrm{\ensuremath{\Gamma}}}_{Z})/2$], respectively, are allowed. In contrast, the operator of dimension 6, OP3, has viable solutions for masses $\ensuremath{\gtrsim}190\text{ }\text{ }\mathrm{GeV}$. For the combination of OP1 and OP3 we obtain solutions (for masses larger than 140 GeV or 325 GeV) that depend on the relative sign between the operators.
