Abstract In this letter, we investigate the production of light dark matter particles at LHC in light of the model (N = 2 SUSY inspired) proposed in Ref. [1] and demonstrate that they will be copiously produced if the colored messengers Fq are lighter than 1 TeV. We expect up to a million events if the Fq mass is about 500 GeV, assuming a ~1 inverse fb luminosity. In addition, we show that, even if the Fq mass is above a few 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 Fq mass range could be constrained using LHC data. This should encourage further studies since they could infirm/confirm the MeV DM scenario.
