Global Constraints on Effective Dark Matter Interactions: Relic Density, Direct Detection, Indirect Detection, and Collider

TL;DR

This paper uses an effective interaction framework to analyze how dark matter particles interact with the standard model, constraining these interactions through multiple experimental data sources including relic density, direct and indirect detection, and collider searches.

Contribution

It provides the most comprehensive limits on effective dark matter interactions by combining diverse experimental data within a unified effective field theory approach.

Findings

Stringent limits on dark matter effective operators from combined data

Constraints from relic density, direct detection, and collider experiments are integrated

Certain interaction models are strongly disfavored by current experimental bounds

Abstract

An effective interaction approach is used to describe the interactions between the spin 0 or spin 1/2 dark matter particle and the degrees of freedom of the standard model. This approach is applicable to those models in which the dark matter particles do not experience the standard-model interactions, e.g., hidden-sector models. We explore the effects of these effective interaction operators on (i) dark matter relic density, (ii) spin-independent and spin-dependent dark matter-nucleon scattering cross sections, (iii) cosmic antiproton and gamma ray fluxes from the galactic halo due to dark matter annihilation, and (iv) monojet and monophoton production plus missing energy at the Tevatron and the Large Hadron Collider (LHC). We combine the experimental data of relic density from WMAP7, spin-independent cross section from XENON100, spin-dependent cross section from XENON10, ZEPLIN-III, and SIMPLE, cosmic antiproton flux from PAMELA, cosmic gamma-ray flux from ${\it Fermi}$-LAT, and the monojet and monophoton data from the Tevatron and the LHC, to put the most comprehensive limits on each effective operator.
