Abstract
We present accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector Dark Matter (DM). We find limits using LHC mono-jet data, spin inde- pendent and spin dependent direct searches, relic density and CMB, and show the interplay between high and low energy data in setting bounds on the parameter space. In order to properly compare data taken at different energies, we take into account the effect of the running and mixing of operators. We also take into account the local density uncertainties affecting direct detection data, and apply EFT validity criteria related to the cut on the invariant mass of DM pair production at the LHC, which turns out to be especially important for the case of vector DM. Finally, we estimate the potential of the future LHC runs to probe DM parameter space.
Highlights
Understanding the nature of dark matter (DM) is one of the greatest puzzles of modern particle physics and cosmology
We have performed a comprehensive analyses of the complementarity between collider and noncollider searches to probe DM parameter space, including LHC monojet data, bounds from spin independent (SI) and spin dependent (SD) direct searches, relic density limits and cosmic microwave background (CMB) indirect constraints due to the injection of energy produced by DM annihilation in the early universe
Since the characteristic energy scale for LHC and direct searches differs by about six orders of magnitude, to correctly evaluate the experimental sensitivity to the DM effective field theory (EFT) operators we have taken into account their running and mixing from the TeV scale to the GeV one
Summary
Understanding the nature of dark matter (DM) is one of the greatest puzzles of modern particle physics and cosmology. Overwhelming observational evidences from galactic to cosmological scales point to the existence of DM [1,2,3], after decades of experimental effort only its gravitational interaction has been experimentally confirmed. No information is available on the DM properties, such as its spin, mass, interactions other than gravitational, symmetry responsible for its stability, number of states associated to it, and possible particles that would mediate the interactions between DM and the standard model (SM) particles. If DM is light enough and interacts
