TL;DR

This paper investigates dark matter interactions with standard model particles mediated by spin-one particles using effective field theory, considering experimental constraints across a broad mass range.

Contribution

It identifies viable operators with antisymmetric tensor mediators that satisfy multiple experimental bounds within the effective field theory framework.

Findings

Operators with antisymmetric tensor mediators are consistent with experimental bounds.

Dark matter particles with masses from MeV to Z boson mass are compatible with the proposed interactions.

The analysis constrains the parameter space for spin-one mediator models of dark matter.

Abstract

We analyze interactions between dark matter and standard model particles with spin one mediators in an effective field theory framework. In this paper, we are considering dark particles masses in the range from a few MeV to the mass of the $Z$ boson. We use bounds from different experiments: $Z$ invisible decay width, relic density, direct detection experiments, and indirect detection limits from the search of gamma-ray emissions and positron fluxes. We obtain solutions corresponding to operators with antisymmetric tensor mediators that fulfill all those requirements within our approach.
