Abstract

We study the prospects of observing the presence of a relatively light Elko particle as a possible dark matter candidate, by pointing out a typical signature for the process encompassing the Elko non-locality, exploring some consequences of the unusual Elko propagator behavior when analyzed outside the Elko axis of propagation. We also consider the production of a light Elko associated to missing energy and isolated leptons at the LHC, with center of mass energy of 7 and 14 TeV and total luminosity from 1fb11 fb^{-1} to 10fb110 fb^{-1}. Basically, the Elko non locality engenders a peculiar signal in the missing energy turning it sensible to the angle of detection.
