Abstract

In this letter, we investigate the production of light dark matter particles at LHC in a N=2 SUSY inspired model and demonstrate that particles will be copiously produced if the colored messengers Fq are lighter than 1 TeV. We expect up to 106 events if mFq≃500  GeV, assuming a ∼1  fb−1 luminosity. In addition, we show that, even if mFq>O(1)  TeV, searches for Fq production at LHC are promising because a kinematical signature can be used to separate the signal from background. This signature is similar to that expected in supersymmetric scenarios. Hence, our study shows that most of the mFq range could be constrained using LHC data. This should encourage further studies since they could infirm/confirm the MeV DM scenario.
