Dark matter signals at the LHC: forecasts from ton-scale direct
  detection experiments
  The complementarity between dark matter searches at colliders and in
underground laboratories is an extraordinarily powerful tool in the quest for
dark matter. In the vast majority of the analyses conducted so far these dark
matter detection strategies have been profitably combined either to perform
global fits in the context of certain particle physics models (e.g. the CMSSM)
or to estimate the prospects for a direct dark matter detection given the LHC
potential of discovering new physics beyond the Standard Model. In this paper
we propose an alternative strategy to combine direct and collider dark matter
searches: employing the potential of the upcoming generation of 1-ton direct
detection experiments, we show that for certain supersymmetric configurations
it is possible to translate the information encoded in an hypothetically
discovered direct detection signal into classes of expected signals at the LHC.
As an illustrative application of our method, we show that for a 60 GeV
neutralino thermally produced via resonant annihilations and identified by a
1-ton direct detection experiment, our approach allows to forecast a clearly
identifiable prediction for a LHC final state involving three leptons and
missing energy. The strategy presented in this paper to systematically
translate a direct detection signal into a prediction for the LHC has the
potential to significantly strengthen the complementarity between these two
dark matter detection strategies.
