Abstract
In this White Paper we present and discuss a concrete proposal for the consistent interpretation of Dark Matter searches at colliders and in direct detection experiments. Based on a specific implementation of simplified models of vector and axial-vector mediator exchanges, this proposal demonstrates how the two search strategies can be compared on an equal footing.
Highlights
We have focused in this White Paper on a concrete proposal for characterizing and comparing Dark Matter (DM) searches in collider and direct detection (DD) experiments, based on the framework of simplified models
The results presented here are based on recent work described in [29] and are defined in the context of Minimal Simplified Dark Matter (MSDM) models, which have four free parameters: the mass of the DM particle, mDM, the mass of the mediator, Mmed, the coupling of the mediator to the DM, gDM, and the coupling of quarks to the mediator, gq
For the example of s-channel vector and axial-vector mediator interactions, we show how to characterize the results of searches for DM particles at colliders and direct detection (DD) experiments in such a way that a comparison between the two approaches can be made on an equal footing
Summary
Since the start-up of the LHC in 2010, collider searches for Dark Matter (DM) particle production, and their comparison with direct detection (DD) scattering experiments such as XENON100 [1] and LUX [2], have become a focal point for both the experimental and theoretical particle and astroparticle communities. Collider searches are generally characterized by their use of ‘mono-objects’, such as mono-jets or mono-photons, accompanied by missing transverse energy [3,4,5,6,7,8,9,10] Until recently, these searches were mainly interpreted in the framework of specific models, such as the ADD [11] or unparticle models [12], or else used an effective field theory (EFT) to allow for the straightforward comparison with the results of DD experiments. A link to the Brainstorming Workshop’s agenda, which includes links to the individual talks, is given in [27] In this White Paper, we propose benchmark scenarios in a particular simplified model framework for DM models and provide examples of plots that will allow for a more meaningful comparison of the results from collider and DD experiments. We became aware of [28], which addresses aspects of simplified models in order to go beyond EFT interpretations of DM searches
